Our Patented INDUCTIVE PUMPS employ the very latest in pump technology. INDUCTIVE PUMPS use electromagnetics to drive a completely encapsulated internal piston creating a positive displacement of the piston within the piston cylinder. By using one-way check valves, both ends of the piston can be used for pumping and suctioning simultaneously. This provides for highly accurate, repeatable, programmable metered pumping. \r\n\r\nSince the polymeric coated internal piston is the only moving part, the INDUCTIVE PUMP is almost maintenance free. It requires no lubrication, eliminating oil or lubricants that can contaminate contents or surroundings. Plug it into 110volt wall plug and you have a "working pump" with immediate on/off and rate control.\r\n\r\nINDUCTIVE PUMPS solve lubrication problems. The Model 1.5 can easily pressurize lubricant taken from the bottom of the sump to appropriate spray pressures. Lubricant rates are adjustable from 30 ml/min to 1.5 gpm. This incredibly simple, self-contained, sealless portable assembly will solve numerous lubrication problems on blower bearings, gear units and large API pump bearings.
