The information below has been compiled to answer our most frequently asked questions about our GPM-Eliminator™ pump line. If you have further questions, it would be our pleasure to help you answer them. Please feel free to contact us.
ARE GPM-ELIMINATOR MOTORS COMPATIBLE WITH VFDS?
Yes. All GPM-Eliminator motors are inverter duty rated for VFD use. We also use Class H insulation to increase the motor insulation life.
HOW LONG CAN A SUBMERSIBLE GPM-ELIMINATOR RUN DRY?
Because we use motors with Class H insulation and we operate the mechanical seal in a full barrier fluid the pumps are capable of running dry. Best practice is to always have the motor submerged for better heat transfer.
WHAT’S THE STANDARD CABLE LENGTH FOR A SUBMERSIBLE GPM-ELIMINATOR MOTOR?
Standard cable length is 33′ (10m). Custom lengths are available.
WHAT ARE SPRAYHOLES?
Sprayholes are simply two holes, 180° apart, designed into the pump casing. They allow a small amount of pumped fluid to spray into the sump area and agitate solids into suspension.
WHICH WAY DO GPM-ELIMINATOR IMPELLERS ROTATE?
Pumps using our Low Head (LH) casing have impellers that rotate clockwise when viewed from the suction end. Pumps using our Even Wear (EW) or Generation Three (GT) casings have impellers that rotate counter clockwise when viewed from the suction end.
ARE GPM-ELIMINATOR PUMPS AVAILABLE WITH QUICK-DISCONNECT STYLE DISCHARGES?
Pumps which need to be removed often for repairs typically use a quick-disconnect discharge and a slide rail. Our customers can easily avoid the expense and maintenance involved with these removal systems. First, GPM-Eliminator pumps do not need frequent repair. Second, by utilizing a readily available, inexpensive, flexible slurry hose, our customers can remove the pump to a working area where the discharge hose can be disconnected.
HOW DO YOU AGITATE EXTREMELY THICK SLURRIES?
GPM-Eliminator pumps are available with mechanical shaft agitation. This device acts like a mixer and aggressively agitates the slurry as it enters the pump.
