Pump specifications Your pump carries a name 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 datasheet. An example name plate is shown below. (the abbreviations on the label are as follows: Pm=maximum pressure, max.=maximum speed, s/n=serial number) 10.1 Standards See "Declaration of conformity"...
Transport Choose the right means of transport according to the size of the pump and the drive. The pump must be suspended correctly for transport. If using a crane or fork-lift truck, the ropes or belts must be sufficiently dimensioned. If the pump is transported with a lift truck or fork-lift truck, note that the unit's centre point is not necessarily the centre of gravity.
Good pump installation practice The motor shaft and pump shaft connection must be guarded to protect the user from contact, when in use. Place the pump on a level surface Do not start the pump without a coupling guard to protect the user from contact. The mounting surface should be strong enough to support the pump.
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 interference vibrations which must be avoided.
12.3 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.
12.4 Possible pump orientations The pump can be positioned in one of eight orientations, and can rotate clockwise or counter-clockwise. 10-02 12-03 02-04 * 03-06 04-08 06-09 08-10 * 09-12 Unless you specify otherwise when ordering, the pump is delivered in position 10-02. Special customised nozzle orientations are possible.
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.
Flushing the seal system In order to prevent a dry run and to ensure a proper working sealing system a seal flush is recommended. 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.
Fitting the static flushing device The static flushing device can be fitted to a Certa Plus pump with a flush ring or a double mechanical seal. See also "Assembling the pump head" on page 34. The connection with the vent pipe must be connected to the highest flush port.
Attention: Keep a minimum distance of 50cm (20 inches) from the pump while performing high-pressure cleaning. MasoSine Certa Plus series pumps are designed to be cleaned in place. Please follow our CIP cleaning instructions below. Maintaining a clean process line is vital to maintaining a high level of hygiene and no contamination of the end-product.
Page 22
CIP. In this case a manual cleaning procedure is recommended. Determine the pump cleaning schedule on-site for materials being processed and plant maintenance schedule. Principally, MasoSine Certa Plus series pumps do not require manual cleaning if CIP (clean-in- place) is performed after operation.
Changing the oil Every day before using your pump, check the oil viewing glass at B in the bearing housing for damage and to confirm that there is enough oil in the end shield. The oil should reach the middle of the glass. Check that the drain plug C is in place and fully tightened.
Heating and cooling option Special versions of MasoSine P100, P200, P250, P300 and P400 pumps can be heated or cooled to maintain the required product temperature within the pump—pumping chocolate or ice cream, for example—by passing fluid at the temperature required through crescent-shaped channels in the pump housing and the front housing.
In some cases it might be necessary to rework the front cover and/or back cover of the pump to smooth out deeper scratches (e.g. surface damage caused by a foreign body). Please contact the MasoSine factory or your local supplier if you require refurbishment. MasoSine can provide you with the necessary data to do a proper refurbishment.
Disassembly and assembly Use the appropriate torque value (see "Tightening torques" on page 41) Before beginning disassembly, disconnect the pump from the mains power, and secure it against unintentional start-up. The photographs shown in the following procedures were taken of a Certa pump of medium size.
Page 27
Removing the locking screw Use the blocking tool (for part number see section "Tools" on page 56) to lock the rotor and the shaft before opening the locking screw on the rotor. Use one of the cap nuts from the front housing to fasten the blocking tool. Open the locking screw using the socket adapter, turning it counter clockwise (for part code see "Tools"...

Carefully remove the rotor and store safely. Take care when removing the rotor to ensure the seal faces are not damaged. The seal faces are brittle To re-assemble the pump, refer to the assembly instructions below, starting with section "Assembling the support / Centering the rotor with the shim ring"...
19.2 Disassembling the mechanical seal system To make the procedure clearer, on some pictures the middle housing has been removed. This is not necessary for regular maintenance. Removing the seal system Carefully remove the back seal face from the mechanical seal system and store it safely. The seal face with O-ring at the outer diameter, which is installed in the pump housing.
19.3 Disassembling the middle housing The middle housing does not need to be disassembled for changing, for example, the Gate or mechanical seal system. It is only explained here for the sake of completeness. Unscrew the nuts which hold the middle housing in place, by turning them counter clockwise. Pull the middle housing off the pump.
Remove the back housing. Rotate the back housing on the end shield to the orientation position you require. Make sure you align the segments on the back housing with the segments on the end shield. Tighten the screws by turning clockwise. 19.5 Assembling the support / Centering the rotor with the shim ring Place the shim ring at the flange of the support.
19.6 Checking the X-Dimension The rotor and locking screw need to be fully tightened using the appropriate torque value (see "Tightening torques" on page 41). Check the X-Dimension by measuring the distance from the rotor to the back housing, from the flat part at the peak of the rotor curve.

Make sure the spring assembly fits into the two notches. Use a screwdriver or similar tool and move the spring assembly axially. If it is locked, it is in position. If you can turn the ring, turn it carefully until it is possible to push it into the notches. Fit the O-ring to the inner diameter of the back housing.
Carefully press the seal face with the side of the cup evenly into the rotor. Make sure that the seal face is pushed all the way in, by pressing it as shown. It is recommended to use a hand press or other suitable tools to ensure correct assembly. 19.8 Assembling the pump head Assembling the middle housing and the front housing Fit the seal in the rear of the middle housing.
