IOM manual Tapflo sanitary series pumps 6

0. GENERAL

0.1. Introduction

The Tapflo Air Operated Diaphragm Pump range is a complete series of pumps for industrial applications. The pumps are designed to be safe, simple and easy to use and maintain. The construction is seal-less and without rotating parts. The pumps are suitable for a variety of duties in hygienic installations.

With proper attention to maintenance, Tapflo Pumps will give efficient and trouble free operation. This instruction manual will familiarise operators with detailed information about installing, operating and maintaining of the pump.

0.2. Warning symbols

The following warning symbols are present in this instruction manual. This is what they say:

This symbol stands next to all safety instructions in this instruction manual where danger to life and limb may occur. Observe these instructions and proceed with utmost caution in these situations. Inform also other users of all safety instructions. In addition to the instructions in this instruction manual, the general safety and accident prevention regulations must be observed.

This signal stands at points in this instruction manual of particular importance for compliance with regulations and directives, for correct work flow and for the prevention of damage to and destruction of the complete dampener or its subassemblies.

0.3. Qualification and training of personnel

The personnel in charge of installation, operation and maintenance of the pumps we produce must be qualified to carry out the operations described in this manual. Tapflo shall not be held responsible for the training level of personnel and for the fact that they are not fully aware of the contents of this manual.

1. INTSTALLATION

1. INSTALLATION

1.1. Operation principle

The Tapflo diaphragm pump is driven by compressed air. The two diaphragms are connected by a diaphragm shaft and pushed back and forth by alternately pressurising the air chambers

behind the diaphragms using an automatically cycling air valve system. The Suction Cycle:  Suction

One diaphragm creates a suction action in one chamber (on the right) when being pulled back from the housing.

 Discharge

The other diaphragm simultaneously transmits the air pressure to the liquid in the second chamber (on the right) of the housing, pushing it towards the discharge port.

During each cycle the air pressure on the back of the discharging diaphragm is equal to the head pressure on the liquid side. Tapflo diaphragm pumps can therefore be operated against a closed discharge valve with no negative effect to the life of the diaphragms.

1.2. Receiving inspection

Although precaution is taken by us when packing and shipping, we urge you to carefully check the shipment on receipt. Make sure that all parts and accessories listed on the packing list are accounted for. Immediately report any damage or shortage to the transport company and to us.

1. INTSTALLATION

1.3. Storage

If the equipment is to be stored prior to installation, place it in a clean location. The pump should be stored in an ambient temperature of 15°C (59°F) to 25°C (77°F) and relative humidity below 65%. It should not be exposed to any heat source e.g. radiator, sun as this could result in a negative way on the tightness of the pump. Do not remove the protective covers from the suction, discharge and air connections which have been fastened to keep pump internals free of debris. Clean the pump thoroughly before installation.

1.4. Foundation

The support of the pump is furnished with mounting holes. Fix the pump on a stable foundation, which is able to absorb vibrations. It is essential for the operation of the pump to mount the pump with the feet in a downward direction (see sketch in chapter 1.8 “Example of installation”).

1.5. Suction and discharge piping

Suction and discharge piping should be fully supported and anchored near to but independent of the pump. The piping to the pump should be a hose, to prevent undue stress and strain on the pump connections and the piping.

1.5.1. Connection of suction pipe

Remember that the suction pipe/connection is the most critical point, especially if the pump is priming. Just a small leakage will dramatically reduce the suction capability of the pump. When connecting the suction pipe, following is recommended.

For satisfactory operation, use reinforced hose (the suction power may otherwise shrink the hose) or other flexible piping. The internal diameter of the hose should be the same as on the suction connection (at the bottom of the pump) to have best suction capability.

Make sure that the connection hose - pump is completely tight, otherwise the suction capability will be reduced.

Always use as short suction pipe as possible. Avoid air pockets which can arise with long piping.

1.5.2. Connection of discharge pipe

For this connection it is only recommended a simple and positive flow connection. Use a hose or flexible piping (minimum one meter) between the discharge connection and any rigid fixed piping. Coil the hose at least one turn. All components (hose, pipe, valves etc.) on the discharge piping must be designed for minimum PN 10.

1. INTSTALLATION

1.6. Health and safety

The pump must be installed according to local and national safety rules.

The pumps are constructed for particular applications. Do not use the pump on applications different from that for which it was sold without consulting us to ascertain its suitability.

1.6.1. Protection

In the interest of health and safety it is essential to wear protective clothing and safety goggles when operating, and/or working in the vicinity of Tapflo pumps.

1.6.2. Explosion hazardous environments – ATEX

The standard Sanitary series pumps are not allowed to operate in environments where there is danger of explosion. Static electricity may occur in the pump under operation, which may cause explosion and injury. Special conductive TX pumps are available for such applications. Follow below instructions and local/national rules for safe use. ATEX (directive 94/9/EC) classification of Tapflo TX pumps:

ATEX II 2 GD IIB c T4

Equipment group: II – all other explosive areas than mines; Category group: 2 – high level of protection (can be used in zone 1); Atmosphere: G – gas; D – dust; Explosion group: IIB – such as ethylene; Type of protection: c – constructional safety; Temperature class: T4 – in the event of a malfunction, the maximum temperature of a surface that may be exposed to gas T4 = 135 °C.

Earth connection of the pump and other equipment

Connect a suitable earth wire to the stainless steel earth connection that is placed on the inside of one of the pump housings. Connect the other end of the earth wire to earth and also make sure that other equipment like hoses/pipes/containers etc. are properly earthed/connected.

1.6.3. Air pressure

The maximum air pressure for Tapflo pumps is 8 bar. Higher air pressure than 8 bar can damage the pump and may cause injury to personnel in vicinity of the pump. If you intend to apply a higher air pressure than 8 bar, please consult us.

1. INTSTALLATION

1.6.4. Noise level

At tests, the noise level from a Tapflo pump has not exceeded 80 dB(A). Under some circumstances, for example if the pump is operating under high air pressure at low discharge head, the noise can be inconvenient or hazardous for personnel staying for long periods in the vicinity of the pump. This hazard can be prevented by:

 using suitable ear protection;  lowering the air pressure and/or raising the discharge head;  leading out the outgoing air from the room by connecting a hose to the muffler

connection of the pump;

 using elastomer valve balls (EPDM, NBR or polyurethane) instead of PTFE, ceramic or

stainless steel, provided that the elastomer is compatible with the pumped liquid.

1.6.5. Temperature hazards

 Raised temperature can cause damage on the pump and/or piping and may also be

hazardous for personnel in the vicinity of the pump/piping. Avoid quick temperature changes and do not exceed the maximum temperature specified when the pump was ordered. See also general max temperatures based on water in chapter 6. “DATA”.

 When the pump is exposed to ambient temperature variations or if there is big difference

between the temperature of the product and the surrounding, the tightening torques of the housing nuts should be checked periodically as part of preventive maintenance.

 If a hot product is pumped, the pump should not stand still when filled for a longer period

of time. This could cause leakage from the valves and contamination and/or damage of the air valve.

 Below 0°C (32°F) plastic materials become more fragile what can cause accelerated wear

of parts made of these materials. This is a hazard that has to be accepted when pumping such cold products. Also in such case, when a pump is not operational it should be drained of all liquid.

 Bear in mind that the viscosity of the product changes with temperature. This has to be

taken into consideration when selecting the pump.

1.7. Air connection

Screw the air hose into the air intake on the centre block of the pump with for example a bayonet coupling. For best efficiency, use the same hose diameter as the internal diameter of the connection on the air intake.

1.7.1. Air treatment system

The air valve is constructed for oil-free air. Lubrication of the air is not allowed. However, if the air is very dry (laboratory air), the air may be lubricated with water. Maximum air pressure is 8 bar. As prevention purpose, a filtration of the air by means of a 5 micron filter or finer is recommended. Recommended air quality according to PN-ISO8573-1:2010 is particles class 6, water class 7 and oil class 4. Dirt in the air can under unfortunate circumstances be the cause of a breakdown. To facilitate the operation of the pump we recommend an air treatment system connected to the air supply. These components should be included:

1) Regulator to adjust the air pressure;

1. INTSTALLATION

2) Manometer to read the actual pressure;

3) Needle valve to adjust the air flow (especially when operating the pump in the lower range of performance);

4) Filter. These components are included in Tapflo’s Air treatment system which can be ordered from us.

1.8. Example of installation

1) Gate valve compressed air

2) Filter and pressure regulator

3) Flexible hose

4) Needle valve

5) Flexible piping

6) Gate valve suction

7) Gate valve discharge

8) Coiled flexible piping

9) Flow gauge

1.9. Recommended installations

The Tapflo pump is flexible in the way you are able to install it.

1.9.1. Flooded

The piping system is designed with a positive suction head. This is the best way of installation where it is necessary to completely evacuate all liquid from the container, or where viscous (thick) products are transferred.

NOTE! Do not exceed 0,7 bar suction pressure! Higher pressure may cause premature diaphragm failure and irregular pump operation.

1.9.2. Self-priming

The Tapflo pump is designed to pull a high vacuum. It is able to evacuate an empty suction pipe without any damage to the pump. The suction lift is up to 5 meters (16.4 ft.) from an empty suction pipe and up to 8 meters (26.2 ft.) from a wetted pipe. The suction capability depends on the pump size (see chapter 6. “Data”).

NOTE!

Even if all above safety instructions are met and complied with, there still exists a minor danger in the event of a leakage or mechanical damage of the pump. In such case the pumped product can emerge on sealing areas and connections.

2. OPERATION

IOM manual Tapflo sanitary series pumps 12

2. OPERATION

2.1. Before starting the pump

 Make sure the pump is installed according to the installation instruction (chapter 1).

 Filling of the pump with liquid before start is not necessary.

 When installation is new or reinstalled, a test run of the pump with water should be

conducted to make sure that the pump operates normally and does not leak.

 When installation is new or reinstalled, check the pump housing nuts tightening torque

(see chapter 6.5 “Tightening torques”). After approximately one week of operation, the torque should be checked again. This is important to prevent possible leakage.

2.2. Starting and operation

 Open the discharge valve.  Note! Considering the suction capacity when air is still in the suction pipe, it is

recommended to start with low air pressure/flow (slowly) at the beginning. This is not necessary if the pump is filled with liquid before start.

 When the pump has been filled with liquid, the air pressure/flow may be raised in order

to increase the suction capacity of the pump.

 The performance of the pump can be adjusted through the air supply by using a needle

valve and a pressure regulator. The performance can also be adjusted by normal flow control on the discharge side of the system.

2.2.1. Dry running

Although the pump is prepared for dry running it is important to have in mind that long periods of dry run may cause damage to the air valve and circlips. Also an empty pump should operate at low speeds – controlled by a needle-valve.

2.2.2. Optimization of the pump lifetime

 Running at full frequency (maximum air pressure/flow) continuously will cause

premature wear of the components. When there is possibility of the pump running dry or/and at full frequency it is recommended to use an air valve with a PET piston. As a general rule, we recommend to run at half of the maximum capacity of the pump. For instance, a T80 pump should run continuous at maximum 40 l/min.

 As stated in chapter 1.7.1 Tapflo recommends to use an appropriate air treatment

system in order to extend the pump’s lifetime.

 If the air humidity is high, use of a water separator or air dryer is recommended.

Otherwise on the air discharge side due to decompression, icing on the muffler can appear causing it to shrink and eventually it can shoot out of its socket.

 If the ambient air is humid, icing can occur outside of the muffler. In such case it is

recommended to use a longer exhaust of the compressed air (ca. 500 mm / 19,7’’).

2. OPERATION

 If there is possibility of freezing at the air exhaust, it is good to pre-heat the air before it

reaches the air intake in order to raise the dew point of the air. NOTE! Make sure that the air temperature does not exceed 50°C (122°F).

 If icing / freezing is still a problem with the standard muffler, we recommend using our

heavy duty metal muffler. Contact us for more information.

2.3. Pump stopping

The pump can be stopped in two ways:

1) By closing of the discharge valve. The pressure from the system will stop the pump

automatically. The pump restarts easily when the valve is opened again. NOTE! When using this method keep in mind that air must be supplied to the pump. This is essential to keep the diaphragms in balance what protects them from premature failure.

2) By cutting off the air supply. NOTE! When using this method make sure that the discharge valve is opened to relief the pumps pressure.

2.4. Cleaning of the pump

2.4.1. CIP – Cleaning In Place

The importance of easy cleaning is especially great in hygienic applications. Tapflo sanitary pumps are designed for CIP (cleaning in place). This allows the pump to be internally cleaned without disassembly. The pump can be cleaned by flushing through with a CIP fluid (usually a mild solution of sodium hydroxide and a sanitizing additive) or by injection of hot steam. The CIP fluid temperature varies, but in the sanitary field, the temperature is usually

about 90°C. Make sure that the CIP fluid is compatible with the materials in the pump/piping

(consult us for further information).

The solution is passed through the system by either the operation of the pump itself, or by a centralized cleaning system. The CIP fluid must pass through the pump at a minimum velocity of 1.5 m/s in the normal flow direction (from inlet to outlet).

It is recommended to run the pump slowly during CIP. This is to obtain pressure balance on

both sides of the diaphragm. Lack of pressure balance will have influence on the pump’s

lifetime. For more information please contact us.

2. OPERATION

2.4.1.1. Drainage of the pump (T80 – T825)

After the CIP procedure, the pump usually has to be drained from the CIP fluid. The Tapflo sanitary series is

supplied with a hygienic stand, enabling 360° rotation of

the pump unit.

1) Disconnect the pump from the piping.

2) Simply loosen the two socket head cap screws (pos. 174

– see chapter 5. “SPARE PARTS”), rotate the pump 180° and let the remaining fluid drain off. The airline may be left connected during this operation.

3) Rotate back to normal position, connect the pump with

the piping and fix the socket head cap screws (pos. 174).

3. MAINTENANCE

IOM manual Tapflo sanitary series pumps 15

3. MAINTENANCE

3.1. When the pump is new or reassembled

If the pump is new or reassembled after maintenance it is important to retighten the pump housing nuts (pos. 37) after a few days of operation.

Make sure to use the right torque – see chapter 6.5 “Tightening torques”.

3.1.1. Performance test

When installation is new, a test run of the pump should be conducted. Gauge the capacity at specific air pressure/flow. This information is useful for checking performance in the future as wear takes place. You will be able to set schedules for maintenance of the pump and to select spare parts to be kept on stock.

3.2. Routine inspection

Frequent observation of the pump operation is recommended to detect problems. A change in sound of the running pump can be an indication of wearing parts (see chapter 3.4 "Location of faults" below). Leaking liquid from the pump and changes of performance may also be detected. Routine inspections should be conducted frequently.

3.3. Complete inspection

The intervals for a complete inspection depend upon the operation conditions of the pump. The characteristics of the liquid, temperature, materials used in the pump and running time decide how often a complete inspection is necessary. Nevertheless, Tapflo recommends to inspect the pump at least once a year. Parts from KIT AIR and KIT LIQ should be changed during inspection. See paragraph 4.7 for detailed KIT content.

If a problem has occurred, or if the pump is in need of a complete inspection, refer to chapters 3.4 "Location of faults" and 3.5, 3.7 "Disassembly of the pump". You are of course warmly welcome to consult us for further help. Parts that are subject to wear should be kept in stock, see our recommendations in chapter

5.12 “Stocking recommendation”.

3. MAINTENANCE

Fig 3.5.10

Press out the air valve [61] by means of a pressing device. Be careful not to damage the brass edges of the air valve.

The pump is now completely disassembled. Check all components for wear or damage and replace if necessary. When air valve is removed from the centre body check the external O-rings (6 x pos. 30) condition and replace if necessary.

3.6. T30 – Assembly of the pump

The assembly procedure is done in the reverse order to the disassembly. Nevertheless there are a few things that you have to remember in order to assemble the pump correctly.

Fig. 3.6.1

When putting the air valve [61] into the centre block [12], apply some water or alcohol on the O-rings to provide smooth insertion of the air valve. It is recommended to use a pressing device for this operation.

NOTE! When inserting the T30 size air valve, replace the shaft with a screw and a nut to make sure the air valve assembly remains properly fastened.

Fig. 3.6.2

When screwing in the diaphragms [15] on the shaft [16], the holes in the diaphragms must align with the holes in the centre block [12]. Sometimes it is necessary to turn the diaphragm back a little bit in order to align the holes.

Fig. 3.6.3

When putting in the pin screws [14] take extra care not to damage the diaphragms [15] with the pin screw thread.

3. MAINTENANCE

Fig. 3.6.4

During assembly of the housings [11] make sure they are in the correct position – the inlet pipe has a valve ball stopper.

Fig. 3.6.5

When fastening the domed nuts, remember to do it according to the tightening procedure and with the appropriate torque. NOTE! After a few weeks of operation retighten the domed nuts with the appropriate torque.

Fig. 3.6.6

When fastening the tri-clamps apply some FDA grade lubricate on the thread.

3.6.1. Test run

We recommend you to conduct a test run of the pump before installing it in the system, so no liquid gets wasted if the pump leaks or perhaps does not start accordingly to wrong assembly of the pump.

After a few weeks of operation retighten the nuts with appropriate torque.

After a few weeks of operation retighten the nuts with appropriate torque.

4. OPTIONS

4.1. Valve options

In T225, T425 and T825 pump sizes flap valves or heavy duty valve cups (not available in T825) are available as an option instead of standard valves.

4.1.1. Flap valves

It is a great option when the product we intend to pump has high viscosity, contains big solids or solids that can be damages by valve balls (e.g. fruits). Mounted with clamps they provide easy maintenance and cleaning. Flap valves made in AISI 316 are mounted in special flap valve cup with clamps between housing and manifold. Pump with flap valves differ from standard pump by valve type, manifolds (pos. 131, 132) and pump housing (pos.11).

IMPORTANT!

Flap valves are not appropriate for pumping water-like products. If a liquid has low viscosity, the valve will open and close very fast with no shock absorption that is provided by viscous products. Also dry running of the pump for longer periods will cause rapid valve wear and eventually pump stopping.

4. OPTIONS

4.1.2. Ball cup valves

This option is a perfect solution when there is risk of damage to the valve seats from the product. If such situation is to occur there is no need to replace the whole manifolds or housings, just the valve cup what drastically reduces the spare parts cost. Just like the flap valve it is made of AISI 316 stainless steel and is mounted between the housing and manifold with clamps. In the same way the manifolds (pos.131 and 132), pump housing (pos.11) and pump stand (pos. 17) has to be changed in comparison to a standard sanitary pump.

4.2. Heating jacket

The heating jacket is a great option when the pumped product tends to solidify at lower temperatures e.g. chocolate or paraffin. When the pump has finished its duty and is left for some time without operation the product can solidify inside. This is when the heating jacket comes in. Before next pump start-up heating medium like water or steam is into the heating system for a defined period of time to melt the product inside the pump. Only then can the pump be started again with no risk of damage.

Recommendations:

 When using steam as the heating agent the flow must

be from top to bottom (due to steam condensation). In case of hot water or other liquid it is the other way around.

 Do not exceed 2 bar pressure in the heating jacket.

For spare parts see chapter 5. Spare parts.

4. OPTIONS

4.3. Magnetic ball lifters

New magnetic ball lifters have been implemented in pump sizes T125 – T425. They are implemented to enable pump emptying when no other draining option is available. Rotating the pump is no longer needed. The balls are lifted by simply attaching the magnets to the pumps manifold. Valve balls are available in AISI 420 magnetic stainless steel or PTFE wits steel core.

Pump emptying procedure:

 Install the magnets on the pump manifolds in the area of the valve seat.  Run the pump slowly.  After a few cycles the pump will start to run dry.  Turn off the pump.  Take off the magnets off the manifolds.

CIP and SIP cleaning procedure recommendation:

During cleaning procedures do not use magnetic ball lifters. When the ball is pulled by the lifter and facing the manifold wall it may trap some liquid to stay inside. NOTE! Remember to run the pump slowly during cleaning procedures to ensure the diaphragms are balanced on air and liquid side.

NOTE!

The ball lifting system is built with high intensity NdFeB magnets therefore all pacemaker carriers must not approach the ball lifting system components! Intense magnetic field can disturb heart pace. What is more, all devices that can be damaged due to intense magnetic field must not be placed in the vicinity of the ball lifters.

It is important not to join the magnets as it might be difficult to separate them form each other. Furthermore, the magnets are fragile and when connected can crumble.

6. DATA

6.1. Capacity curves

The performance curves are based on water at 20°C.Other circumstances might change the

performance. See below how the capacity will change at different viscosities and suction lifts.

Example (see the red line below): A flow of 30 litre/minute is desired. The discharge pressure is calculated to 25 mWC. We choose a T80 pump. It requires an air pressure of 4 bar and will consume approximately 0.20 Nm3 of air per minute.

Recommended flow is half of the max flow, e.g. recommended flow for a T80 is 40 l/min.
