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.

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
lIf 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.
lThe pump may have been contaminated during transport. Remove the pump
front cover and clean if necessary before start-up.
lBefore 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.
Fluid
level
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.
lCast 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.
lStainless steel power frame: Make sure that the correct flush ring is installed
with tube connections and circulate flushing fluid through the system.
lThe 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.
lThe pump should be flushed without pressure: the flushing fluid should be
allowed to drain from the system without pressure.
lFill the pump with liquid to prevent it from running dry, possibly via a separate
intake valve connected to the suction or pressure pipe.
lIf 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.
MasoSine SPS sinusoidal pumps User Manual 29

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.

18 Heating and cooling option
Special versions of MasoSine
SPS 100, SPS 200, SPS 250, SPS 300,
SPS 400 and SPS 500 pumps can be
heated or cooled to provide the correct temperature for your process—
pumping chocolate or ice cream, for
example—by passing fluid at the temperature required through crescentshaped channels in the pump housing
and the front housing. The pump has
1/4in or 1/8in connections on two
sides through which the heating or
cooling agent flows. The position of
the connections varies depending on
the model. Counter pressure should
not exceed 1 bar.
Note: Most pumps can be retro–fitted
to allow heating and cooling.
Note: The connections on the front cover
may hinder some maintenance work at the
pump. In most cases, the heating / cooling of
the pump housing is sufficient. Maintenance is
not hindered by the connections.
