Gusher

Since 1913, Gusher has grown their centrifugal pump product lines into one of the largest selections available from a single manufacturer with the Rumaco, Ruthman, and Gusher pump brands.  Models include close-coupled pumps, end suction pumps, immersed pumps, self-priming pumps, vortex pumps, sludge pumps, multi-stage pumps, and full cantilever pumps. Gusher has expanded their product lines farther by offering custom pump designs to suit your application. Many of the pumps come in vertical and horizontal styles, suited for small and large flow rates and the multistage pumps are capable of heads over 800 ft. Multiple applications and specifications are available including, Din specifications, ANSI specification, machine tool and centralized coolant systems, automatic paint systems, industrial spray washers, filtration systems, phosphate, bonderizing, and many more.

Under the name of Ruthman Companies, every employee, vendor and subcontractor, shares a common goal of quality and reliability at an affordable price. Because they listen to customer needs and requests, they have been able to demonstrate innovation and flexibility with their products. See below to discover how Gusher’s horizontal and vertical coolant pumps, multistage pumps, self-priming pumps, machine tool tank units, Din pumps, ANSI pumps, and many others can meet your application needs and exceed your expectations.

7550 / 7600 Vertical Heavy Duty Pumps

7550 / 7600 Vertical Heavy Duty Pumps

Gusher offers the 7600 series top pull out series, enclosed column, vortex, slurry, and the 7550 series vertical end suction centrifugal pumps. These vertical pumps completely remove the need for a seal, there is no alignments required, and require less floor space. The 7600 is designed to minimize maintenance by making the rotating element removable without disturbing the mounting plate or piping. The pump can be either chair mounted or barrel mounted. Applications include spray booths, filtration systems, paint systems, spray washers and many more.

  • Flows up to 10,000 GPM
  • Heads up to 230 ft
  • Temperatures up 1000° F
Coolant Pumps and Tank Units

Coolant Pumps and Tank Units

Gusher coolant pumps include immersed, flange mounted, Rumaco pumps, tank units, and replacements for imported machine tools. Immersed types have 5 configurations to meet you inlet and out let style needs, with single, dual, and stand pipe inlets. Flanged mounted types are best when space is limited and an immersion cannot be used and has both external and internal discharge options.  Rumaco pumps are centrifugal, open impeller type pumps with features such as self-adjusting seals to help installation, throttling without increasing motor load, flange and pipe inlets types, and a wide range of sizes for any application. Tank units are available in 10 to 200 gallons with pumps from 1/25 through 7.5 HP and can be used as permanent, portable, or auxiliary coolant systems.

Horizontal ANSI / DIN 7071 Series Pumps

Horizontal ANSI / DIN 7071 Series Pumps

The DIN and ANSI centrifugal pumps feature standardized engineered parts to ensure interchangeability enabling quick and easy conversion of the pump assembly to you application. DIN pumps are designed to match the DIN 733 standard dimensions and the volute inlet and outlet flanges are made according to the PN16 standard. The ANSI pump is designed to ANSI 73.1 styling with ANSI 16.5 flanges.
