Blackmer, part of PSG, a Dover company in positive displacement, regenerative turbine and centrifugal pump, and reciprocating compressor technologies, says that its new SGLWD Series Sliding Vane Pumps with double mechanical seals are now available.

Available in two sizes – SGLWD3 and SGLWD4 – Blackmer SGLWD Series pumps have been specially developed to provide zero leakage, thanks to an exclusive cartridge type, double radial seal design that is field-proven to offer long life and reliable service in a wide range of critical and high-vapor pressure applications, including those for propane autogas.

Featuring a sliding vane design, SGLWD Series pumps deliver a highly efficient performance over a wide range of temperatures and differential pressures, while eliminating many of the typical problems for gear pumps by providing increased pump life, improved offloading times and line stripping capabilities, the company says.

According to Blackmer, these pumps feature “ductile iron construction, with an internal relief valve; excellent self-priming and dry run capabilities; replaceable wear resistant, hardened casing liners and end discs that allow for easy rebuilding of the pumping chamber to like-new condition; and a symmetrical bearing support that assures even loading and wear for long pump life.”

In addition, SGLWD Series pumps have been designed with a cavitation suppression liner for reducing the noise, vibration and wear normally caused by entrained vapors.

SGLWD Series pumps are available with flow capacities from 133 gpm to 270 gpm at working pressures up to 525 psi, the company adds, and they can be used with mechanical seal flush plans 53A, 53B and 53C.
