Designed to meet the strict handling requirements of Diesel Exhaust Fluid (DEF), Blackmer says 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. Blackmer says 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, Blackmer says, 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.
