Storage

This product has an extended shelf life. However, plastic parts and elastomeric
parts should be stored in a cool, dry environment. The blue polyamide gate should
be stored in cool, clean water if it will be out of use for more than four weeks. Care
should be taken after storage to ensure that all parts function correctly.

5 Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic
chemicals or any other substance hazardous to health must be decontaminated
before it is returned to MasoSine or its distributor.

A certificate included at the rear of these operating instructions, or signed state­ment, must be attached to the outside of the shipping carton. This certificate is
required even if the pump is unused. See 28 Decontamination certificate.

If the pump has been used, the fluids that have been in contact with the pump and
the cleaning procedure must be specified along with a statement that the equipment
has been decontaminated.

If a returned pump requires cleaning, a charge will be made. Internal parts that have
not been decontaminated will be replaced and a charge will be made.

6 Sinusoidal pumps—an overview

The functioning principle of MasoSine pumps is ingeniously simple.
The pump consists of modular components.
The sinusoidal rotor creates a chamber within the pump body four times per revolu-

tion, in which the pumped fluid is displaced. As a filled chamber rotates, it contracts,
closes and discharges its contents. At the same time, the opposite chamber opens
by the same fraction of a millimetre to draw in more fluid. The result is a pump free
of pulsation.

The gate works as a seal between the pressure side and the suction side of the
pump. It prevents an equalization of the pressure created by the rotor, stopping it
escaping to the suction side.

8 Safety notes (ATEX)

If your MasoSine pump is to be used in production machinery in potentially explosive
atmospheres, it will be equipped accordingly from the factory.

8.1 Safety signs

II 2 G c T4

Grounding symbol

Pump classification

MasoSine pumps are designed for continuous duty and are therefore assigned to the
Device Group II – Application field “dust – or gas – explosive areas”.

Zone classification

MasoSine pumps can be used in explosive areas of zone 1 / 21. This corresponds to
the category 2 G / D.

It is expressly forbidden to use the pumps in zone 0.

Classification of explosive atmospheres

A distinction is made between dust and gas explosive atmospheres. In the model
code, the atmosphere is abbreviated with G (Gas) and D (Dust). MasoSine pumps
are designed to be used in explosive atmospheres G (Gas) and D (Dust).

Ignition protection

II 2 D c T = 120C

MasoSine pumps pumps are subject to ignition protection “c” constructive safety,
according to the standard for non-electric appliances for use in explosion-risk areas,
EN 13463-5.

Temperature classes

l EX II 2 G c T4 ≥ 135C

l

EX II 2 D c T = 120C

MasoSine SPS sinusoidal pumps User Manual 13

8.2 Earthing the pump

SPS pumps are equipped with an earthing point.
The pump must be earthed by an earthing cable

secured to the correct position. SPS 100 must
be earthed at the base of the rear foot. Other
models must be earthed as shown: with cast iron
power frame, right; with stainless steel power
frame, below right. This is particularly important in
potentially explosive atmospheres.

In addition to earthing the pump, the
drive motor must also be earthed. If the
drive is not earthed,
the pump unit may not

be operated.

8.3 Material properties

The plastic parts fitted inside the pump react more to temperature changes than
stainless steel parts. For this reason, the specified maximum fluid temperature for
which the pump is designed must not be exceeded. This temperature is included in
your purchase documents. If the specified temperature is exceeded, linear expan­sion may block the pump; this in turn could cause the pump to fail or could result
in damage to parts of the pump. In addition, excessive temperatures can accelerate
the wear of dynamic parts and reduce the life of plastic parts.

Corrosion may occur to a pump’s cast iron power frame if the paintwork is damaged.
Corrosion represents a hazard for the use of pumps in potentially explosive
atmospheres (for measures, see 20 Troubleshooting).

Pumps with a stainless steel power frame are not subject to power frame corrosion.

8.4 Pressure conditions

A pressure controller must be installed to avoid over-pressure in the pump as a
result of a closed pressure line.

8.5 Maintenance and repair

l Fill the pump with product before starting only outside the explosive atmos-

phere area. All tools used should comply with ATEX regulations.

l

The pump unit must be kept free of dust with a damp cloth: accumulated dust

can smoulder.

l

The flushing channels in the power frame must be free of blockages and, if

necessary, cleaned.

MasoSine SPS sinusoidal pumps User Manual 14

8.6 Cleaning the pump

No solvent cleaning agents may be used to clean the pump as they
could create an uncontrollable explosive atmosphere.

8.7 Medium to be pumped

Carbon disulphide and chemicals that are combustible below 120C must not be
pumped.

8.8 Coupling

If the pump is used in potentially explosive atmospheres, it must be coupled to the
drive by means of an elastic, positive coupling with ATEX certification for use with
the pump. Chains, toothed belts, V-belts or similar equipment which may transmit
radial forces to the bearings should not be used.

8.9 Drive

Any reduction gears in the drive chain and control units must be ATEX-certified for
use with the pump. Combustion engines must never be used.

An inverter must be installed away from potentially explosive atmospheres, or have
the same ATEX certification as the pump. In any case the inverter must have the
properties required for operation in potentially explosive atmospheres: temperature
monitoring, speed limitation, etc.

9 Pump specifications

Your pump carries a type plate on the bearing housing. It includes a serial
number, which identifies the features of the product. The serial number also
appears on the technical data sheet.

12 Connection to the piping

Before connection, clean the piping and remove foreign bodies such as weld­ing residues.

Fit elastic intermediate members (compensators) between pump and fixed
piping on the suction and pressure sides, to stop pump vibrations being
transmitted to the piping system.

Avoid forces and torques acting from the piping on the pump connections
(e.g. distortion, expansion due to temperatures etc.).

The piping on the pressure side of the pump should run upwards from the
pump, so that residual liquid can flow back into the pump when pumping
stops, and total dry running is avoided. Fluid left in the pump facilitates suc­tion when pumping re-starts.

The user must ensure that a pressure rise above the pressure agreed in the
purchase order and listed in the technical data sheet is not possible.

MasoSine pumps normally run with such a low resonant frequency that no
damage results. However, particularly when running with inverters, certain
frequencies can cause inter ference vibrations which must be avoided. It is

important during commissioning to ascertain whether such vibrations exist
and to define them, so that the inverter can be programmed to avoid these frequen­cies. Similarly, interference from cavitation or rigid lines must be avoided. See 12.1
Cavitation.

MasoSine SPS sinusoidal pumps User Manual 23

12.1 Cavitation

Cavitation is a problem in certain devices where fluid interacts with a moving sur­face. It can occasionally occur in sinusoidal pumps.

Where a surface moves through a fluid, low pressure areas are formed on the sur­face. The faster the surface moves, the lower the pressure around it can become.
If the static pressure of the liquid falls below its vapour pressure, vapour bubbles
form on the pressure side. These implode, causing very high, short-term pressure
peaks up to several thousand bar. These pressure peaks can cause material erosion
and are noisy.

To identify cavitation

If the pump is very noisy and vibrates vigorously, along with the pipe system
attached to the pump, cavitation is likely to be the cause.

To avoid or remove cavitation

Increasing the inlet pressure on the suction side, installing a larger diameter or
shorter inlet pipe or slowing the pump may solve the problem. Make sure that the
pump is not starved of duty fluid at all times.

Cavitation can destroy the pump. The operator must
ensure that the pump can work free of cavitation.

l

Remove the three bolts and
washers using a 13mm spanner. As each
bolt is withdrawn, a spacer between the
baseplate and the pump will fall out.

l

Three sets of threaded fixing points
are provided on the pump; the central
set (pictured in use above) allows the
inlet and outlet ports to be positioned
at 10-2 or 2-10; the other sets (one fix­ing point arrowed) allow the pump to be

positioned with the inlet or outlet horizontal and the other port vertical.

l

Pass the bolts with washers through the baseplate and the spacers (Note: the

longer bolt and the longer spacer secure the baseplate to the bearing
housing at the rear of the pump). Screw the bolts into the set of fixing points
appropriate for the desired pump orientation. Tighten to 25Nm using a 13mm
spanner.

Note: If the direction of flow is also changed, the gate and gate guide must be
reversed. See 13.2 Changing rotation direction.

MasoSine SPS sinusoidal pumps User Manual 25

Take care that fluid in the pressure line leaves the pump in an upward direction, so
that when pumping stops, some fluid remains in the pump. This will make it easier
for the pump to draw in viscous products when pumping restarts. This applies
particularly when the pressure connection is horizontal: positions 12-3 and 12-9.
Take care that the pressure line is run so that the pump rotor is always covered with
fluid, and dry running is avoided.

13.2 Changing rotation direction

When the direction of rotor rotation is reversed, the suction side and the pressure
side of the pump are exchanged. The orientation of the gate and the gate guide
must be changed, too, or the pump cannot pump efficiently. The pump can run for

only a short time with the gate and the gate guide wrongly oriented, and it
will not achieve more than 2 bar pressure. See 22 Dismantling and assembly.

SPS 100 is shown here. All models are similar.

14 Connecting this product
to a power supply

The motor must be connected according to local regulations by a qualified
person. See the instruction manual supplied with your drive motor.

15 Start-up and operation

lIf you are starting the pump for the first time, or have performed cleaning or

repair work, check first that all screws are correctly and completely tightened.

lThe pump may have been contaminated during transport. Remove the pump

front cover and clean if necessary before start-up.

lBefore you start the pump, check that the gate and the gate guide are in the

correct orientation in relation to the suction side and the pressure side of the
pump. (See 13.2 Changing rotation direction).

Observe the appropriate regulations if hazardous fluid is
to be pumped.

Ensure that the pump is installed in an appropriate
position with all necessary safety guards and
precautions (sensors, switches, pressure gauges, etc).

MasoSine pumps must be primed before use.
Before commissioning and during operation, the
pump must be filled with fluid, with the fluid level
above the rotor (see diagram). This can be done
manually through a side channel of your system’s
pipework, or by using a vacuum device where very
viscous fluids are to be pumped; contact MasoSine
for further information. The need to prime can
be avoided by leaving product in the pump after
it is stopped; by leaving CIP or SIP fluid in the
pump after cleaning. For ATEX use, fill the pump
away from potentially explosive atmosphere, and
be aware that if the pump runs dry, the tem-

perature limit for the explosive area may be
exceeded.

MasoSine SPS sinusoidal pumps User Manual 27

Make sure before start-up that all valves on the
pressure and suction sides are open. The pump must
not pump against a closed valve without an over­pressure valve.

If the pump leaks, stop pumping as quickly as possible
and replace the damaged sealing elements. See 22
Dismantling and assembly and 25.2 Seals.

The operator must ensure that the pump can work free
of cavitation. Cavitation can destroy the pump. See

12.1 Cavitation.

16 Flushing the seal system

Flushing fluid at atmospheric pressure—usually water—flushes the area behind the
seal system and prevents the product from hardening and damaging the seal sys­tem. If a static flushing device is fitted, the flushing fluid fills the area behind the
seal.
lCast iron power frame: If no static flushing device is fitted, adapt a fitting and

a tube to the threads of the intake and outlet in the power frame (see diagram
below; models differ) and circulate flushing fluid through the system.

lStainless steel power frame: Make sure that the correct flush ring is installed

with tube connections and circulate flushing fluid through the system.

lThe flushing medium must be at least suitable to the product being pumped. It

should not contain abrasive particles, which would damage the seals. We
recommend that transparent plastic tubes are used as flushing tubes.

lThe pump should be flushed without pressure: the flushing fluid should be

allowed to drain from the system without pressure.

lFill the pump with liquid to prevent it from running dry, possibly via a separate

intake valve connected to the suction or pressure pipe.

lIf your pump is set up for permanent flushing, always check the intake and

outlet (see diagram below).

16.1 Static flushing
device

Intake

Before commissioning, fill the
flushing device (if supplied) with a suit­able flushing fluid, depending on the
product being pumped. Fill the sight glass
with flushing fluid until the fluid level is
just below the bend in the outlet pipe.

Note: The diagram shows a flushing
device fitted to a pump with a cast iron frame. Pumps with stainless steel frames
are similar.

17 Cleaning and sterilisation

MasoSine SPS pumps may be cleaned in place. Please follow our CIP cleaning
instructions—see below.

Maintaining a clean process line is vital to maintain a high level of hygiene and no
contamination of an end-product. Contamination costs time and money.

The heat or chemical reaction from clean-in-place (CIP) and steam-in-place (SIP)
cleaning processes damages a living cell’s essential structures, including the cyto­plasmic membrane, rendering the cell no longer viable.

The process automatically re-circulates cleaning detergent and rinse solutions.

The benefits of clean-in-place (CIP) and steam-in-place (SIP)

l

Cleaning is faster

l Cleaning is less labour-intensive
l Cleaning is repeatable
l There is a reduced chance of operators being exposed to hazardous chemicals

Clean-in-place (CIP) for MasoSine products

Clean-in-place (CIP) is a method of cleaning the interior surfaces of pipes, vessels,
process equipment and associated fittings without disassembling.

The CIP procedure

l

Before the CIP process begins, a preliminary clean should be performed at

maximum speed with no back pressure. This will remove most of the residual
product.

l

Suitable cleaning fluids for the CIP process may include concentrations below

1% of additives. They may be:

l

Sodium hydroxide in distilled water

l Nitric acid in distilled water
l Phosphoric acid in distilled water
l CIP cleaning can be carried out between 80°C and 90°C as standard.
l Cleaning should be done at maximum pump speed to achieve a good cleaning

result.

l

It is very important that the differential pressure on the discharge side of the

pump is at least 3.0 bar / 43.5 psi higher than the pressure on the suction side
of the pump during the CIP process.

Attention: Keep a minimum distance of 50cm from the pump while
performing high-pressure cleaning.

Steam-in-place (SIP) for MasoSine products

Steam sterilisation kills micro-organisms through the application of moist heat
(saturated steam) under pressure without disassembly.

l

Sterilising the pump with standard equipment is possible up to 120°C only at

standstill.

l

The pressure should be high enough to ensure that the steam reaches all parts

of the static pump through the existing clearances.

Key CIP and SIP safety information

l A distance of one metre around the pump should be kept clear during SIP to

minimise danger in case of leakage.

l

CIP and SIP processes should be monitored continuously.

l If a leak occurs during CIP or SIP, the pumphead should not be touched until

system pressure has been relieved and the pumphead has been allowed to cool
down.

l

Ensure that an acclimatisation period is observed after SIP before the pump

process is started. The temperature inside a standard pump should not exceed
85C (176F) during operation.
