Blackmer® Introduces SX1B-DEF Series Sliding Vane Pump For Use in DEF Fleet-Refueling and Tote Applications

Blackmer®, part of PSG®, a Dover company, and a global leader in positive displacement, regenerative turbine and centrifugal pump, and reciprocating compressor technologies, is pleased to announce the introduction and availability of its SX1B-DEF Series Sliding Vane Pump. The SX1B-DEF pumps have been designed to met the strict handling requirements of Diesel Exhaust Fluid (DEF). All of the pump’s materials are either DEF-approved or have been tested to ensure there is no fluid contamination or leeching into the DEF fluid.

The SX1B-DEF model is part of Blackmer’s DEF-pump family, joining the STX2-DEF, STX1220-DEF and STX3-DEF models to give users flow-rate options ranging from 10 gpm to 250 gpm (38 to 946 L/min). The SX1B-DEF model has a small, compact design that makes it ideal for truck-mounting and for use in fleet-refueling or tote applications.

What further differentiates the SX1B-DEF model from competitive models is a choice of 12-volt and 110-volt motor options. The 110-volt version is available with a 50- and 60-Hz dual-rated motor.

One unique feature of the SX1B-DEF pump is the incorporation of a 316 stainless-steel motor shaft as the pump shaft. The Zytel® plastic rotor is installed on the motor shaft and locked into place with a grub screw. Other features of the SX1B-DEF pump are a C-face pump mounting; motor-speed capabilities up to 1,750 rpm; easily maintained and replaceable Duravanes; commercial mechanical seal; and 1” NPT and 1” BSPP tapped-port options.

Blackmer will be showcasing the new SX1B-DEF Series Sliding Vane Pump in Booth No. 4120 at The NACS Show 2017, which will be held from Oct. 17-20 at McCormick Place in Chicago, IL.
