Bulk Transfer Pumps
Designed for the transfer of Motor Oil, Gear Oil, Transmission Fluid, Hydraulic Fluid and 100% Antifreeze, these versatile pumps offer flexibility, economy and simplicity. A unique patented gear and rotor design provides for efficient positive displacement pumping. This, in conjunction with a specially designed bypass allows for the transfer of a wide range of fluids up to a viscosity of 3,150 cps. Liquidynamics Bulk Transfer Pumps are designed to automatically minimize current draw by responding to increases in viscosity by limiting output flow, thus staying within the amperage limitations imposed by 115 VAC power sources. Other configurations available, contact Liquidynamics for more information. Any of the Transfer Pumps below may be fitted with the optional “PowerMaster” control by adding a ‘P’ suffix to the base number, i.e.; P/N 33280 with PowerMaster becomes P/N 33280P. See PowerMaster control option for features and benefits.
