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.
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.
Before start-up, make sure that all valves on the pressure and suction sides are
open. The pump must not pump against a closed valve without an over-pressure
valve.
If the pump leaks, stop pumping as quickly as possible and replace the damaged
sealing elements. See See Disassembling the mechanical seal system on page 28.
The operator must ensure that the pump can work free of cavitation. Cavitation can
destroy the pump. See See Cavitation on page 15.
