WARNING
A VORTEX BREAKER, SCREEN, AND/OR BAFFLE MAY BE REQUIRED IF
THE TANK IS SMALL OR THE BYPASS RETURN LINE IS TOO CLOSE TO
THE PUMP SUCTION LINE.
Block valves are required in the bypass line if the line enters the reservoir
below the fluid surface.
3.
FILTRATION
As a minimum recommendation, install a 100 Mesh (149 Micron) strainer or
equivalent filtration device in the suction piping adjacent to the pump to prevent
mill scale, rust and other foreign material from damaging the pump.
WARNING
THE ROTO-JET PUMP IS NOT DESIGNED TO PUMP ABRASIVES AND IS
NOT WARRANTED AGAINST ABRASIVE DAMAGE OR WEAR. IT WILL
NORMALLY OPERATE SATISFACTORILY WITH UP TO 100 PPM
SUSPENDED SOLIDS, BUT WEAR WILL DEPEND ON THE PARTICLE SIZE
AND HARDNESS. CONSULT FACTORY FOR FILTRATION AND SPECIAL
PARTS RECOMMENDATIONS IF THIS LEVEL IS EXCEEDED.
4.
SEAL DRAIN
In the event of seal failure, the leakage will exit from the seal drain. Piping may
be connected to the seal drain (except the RG 2x2) and piped away from the
unit, but it should never be plugged. If pumping other than water, please
consult the factory. Leakage should be monitored for identification of seal
failure.
5.
SEAL FLUSH
Unless the pump was equipped for seal flush, the seal flush inlet should remain
plugged. If seal flush is necessary, the tubing or piping should be connected to
the seal flush inlet. It is recommended that the flush fluid be supplied at 2-3
gpm (.5-.7 m3/hr) flow rate and 15-20 psig (1-1.4 bar) pressure above the inlet
pressure. Flush fluid temperature is dependent on pump duty and temperature
of pumped fluid. Please consult factory.
