PSG’s Blackmer sliding vane pumps

Vane pumps are 24% more efficient than gear pumps,
estimated $552 - $1,771 energy cost savings.

  Blackmer Pumps

Problem

Poor pump design, pump selection, and improper system operation can result in higher energy costs.

Solution

By eliminating the need to increase the pump speed over time, sliding vane pumps save additional energy when compared to gear pumps. Sliding vane pumps are inherent energy savers by virtue of their design.

Annually, sliding vane pumps can account for $552 - $1,771 in energy cost savings when compared to internal gear pumps.
