9.15 Limit values for the pump
The pump’s maximum speed, maximum pressure and maximum temperature are included in the technical
data sheet supplied with each pump. These limit values must not be exceeded in any circumstances. This
applies in particular when using a frequency converter.
If pump is supplied without a drive, the following values apply:
C800
Maximum pressure*
15 bar/217 psi
Maximum speed*
400rpm
Maximum temperature*
100C/212F
Minimum temperature*
-20C/-4F
* These limits may vary, depending on the drive, the application and the rating of the pump. (See your
purchase order confirmation, or contact MasoSine and quote your pump’s serial number.) On customer
request, higher pressures and temperatures are possible.
9.16 Maintenance and repair
Maintenance and repair work on the pump should only be carried out by trained service personnel, who
should have read and understood this manual prior to installing, operating or servicing this equipment.
Inform operating personnel before starting maintenance and repair work. Protect all plant parts and
operating media connected before and after the machine, such as compressed air and hydraulics, against
unintentional start-up. In all maintenance, inspection and repair work, switch the machine off and secure
the main switch against unintentional start-up.
Secure larger assemblies carefully to lifting gear. Check loosened screw connections for firm seating. Use
only original spare parts.
After maintenance work is finished, check the safety devices are functioning.
Bearings maintenance
Note: Remove the bearing housing only to replace or adjust the shim ring. Do not attempt to
dismantle the power end of the pump or replace the bearings. Pumps needing repair, servicing,
new bearings or other work on the power end must be returned to MasoSine for attention. Special
training is available. Please contact MasoSine for further information.
Bearing replacement intervals:
The table below shows the recommended intervals in hours, for renewing the bearings subject to the
maximum speed and pressure, as listed in the table See Limit values for the pump above
