REXROTH “S” SERIES GEAR PUMPS
Rexroth’s gear pumps consist of precision finished steel gears enclosed in a cast aluminum housing. Equipped with a patented pressure loading principle for high overall pump efficiency. The original S Series featured a floating wear plate design permitting improved internal pump sealing for high volumetric efficiencies due to reduced internal leakage and delivering improved horsepower utilization.
Hydraulic.net offers replacement pumps for the Rexroth “S” series for the following models:
S12 |
S16 |
S20 |
S30S |
S30A |
The model S pumps are self-priming, external gear pumps. Rated to 3000 PSI (210 bar) service with drive speeds to 3500 RPM. The hydrostatically loaded wear plate system ensures the volumetric efficiencies remain consistently high over the useful life of the pump.
Some Rexroth pump series offer a variety of functional options which are available as either standard or special order, such as built-in relief valves, flow control valves, flow divider valves, and dual pumping element combinations.
The Rexroth has delivered quality, expertise, and innovation over the last four decades. In the beginning, it was a small talented group of determined people who set out to offer the finest industrial products available to U. S. manufacturers.
Between 1967-1974 Rexroth concentrated on sales of industrial hydraulics and built a network of distributors nationwide. In 1976, Rexroth became a subsidiary of Mannesmann AG. The company continued to grow and expand; purchasing Mobile Hydraulics division from Borg Warner and in 1995 Rexroth’s US sales exceeded $500 million for the first time. In 1998, Alfred J Krug, 1st President and CEO of Rexroth retired after 30 years of service. Rexroth was later acquired by Bosch Rexroth and merged the brand with Bosch Automation Technologies.
The S series pump is no longer in production from Rexroth or Bosch Automation Technologies. Finding parts for the original series pumps is challenging. Hydraulic.net is a manufacturer building gear pumps to order for the S series based on the original OEM specifications. With over 30 years of experience and an ISO9001 Quality System manufacturer; previously certified by every major manufacturer in North America including Caterpillar, John Deere, Case New Holland etc. We are your direct resource for Rexroth S series pumps for the S12, S15, S16, S20, and S30 models.
