SK41906 and SK41982

Webster now has available a Mini waste oil pump. Webster's waste oil pumps are available in single stage 3450 rpm models, rated at 20 gph.for the SK41906 and 25 gph for the SK41982. Operating pressure is factory set at 100 psi. These waste oil pumps are able to maintain its recommended flow rate throughout the 100 to 150 psi pressure range.

1RR140D-4EK13


This single stage waste oil pump operates @ 1725 rpm. The operating pressure range is 0-40 psi., with a blocked nozzle rated pressure rang of 23-40 psi. Flow rate generally runs 7-15 gph. Maximum inlet vacuum 10" Hg. Viscosity range is 34-7000 SUS (2.5 Centistokes), temperature range 40 F (min) - 160 F (max). This unit incorporates a 31/8 in long shaft from mounting face to shaft end and can be hub or flange mounted. The pump can be used on one or two pipe installations. Double lip type Viton seals assure low starting torque and provide positive protection from leaks. This fuel unit utilizes the unique Webster rotary filter to minimize maintenance. UL Listed for waste oil and #4 or lighter fuel oils.
