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
•
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.
•
The pump may have been contaminated during transport. Remove the pump front cover and clean
if necessary before start-up.
•
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 "Possible pump orientations"
on page 24).
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.).
Fluid
level
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 temperature limit for the
explosive area may be exceeded.
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 over-pressure
valve.
If the pump leaks, stop pumping as quickly as possible and replace the damaged
sealing elements. See "Disassembly and assembly" on page 38 and "Seals" on
page 119.
The operator must ensure that the pump can work free of cavitation. Cavitation can
destroy the pump. See "Cavitation" on page 23.
