2.0 BASIC OPERATION
Your Murzan Pump has wetted parts constructed of 304 or 316 stainless steel and FDA approved
elastomers.
When using the pumps in a permanent installation attached to rigid piping, the use of flexible
couplings on both the suction and discharge ports of the pump is recommended to reduce
vibration due to the reciprocating nature of the pump.
All fittings must be tight in order to eliminate air and product leaks. This will allow the pump to
run as efficiently as possible.
The suction pipe diameter should never be less than the diameter of the suction manifold. Larger
diameters may be used if extremely viscous materials are to be pumped.
Non-collapsible reinforced hose must be used on the suction side of the pump if hoses are to be
used in place of piping.
Should you need to control your pump discharge rate, you may do so by:
1.
Limiting the volume and/or pressure of the air supply to the pump. An air regulator
installed at the air inlet will serve this purpose.
2.
Throttling the pump discharge by installing a valve in the discharge line of the pump.
When the discharge pressure equals or exceeds the air supply pressure, the pump will
automatically stall, eliminating the need for pressure relief valves. Pump damage will not
occur when the pump is stalled.
Caution: Do not exceed 100 psig air supply pressure.
Caution: Maximum temperature limits are based upon both mechanical and corrosive
factors. Certain products will significantly reduce maximum safe operating temperatures.
Please consult the factory when product compatibility is in question.
