Graco SoloTech Peristaltic Hose Pumps See all Brands

Grace EP Hose Pumps


Graco's SoloTech (ST) series offers one of the most advanced technology seen in peristaltic hose pumps.

Graco's ST Hose pump design utilizes a single roller that compresses an engineered hose through a full 360 degrees of rotation. This innovative design means longer hose life when pumping caustic, abrasive or sensitive materials for metering or transfer.

ST Peristaltic Hose Pump Overview

 

Features

  • New metallic roller with bearings provides constant compression and flow
  • More flow per revolution than conventional designs
  • Cast aluminum housing reduces pump weight
  • Inexpensive to maintain
  • ST 10
  • ST 23
  • ST 26
  • ST 30
  • Hose Variations

SoloTech 10 Peristaltic Pump

Product Description

The ST10 is the smallest of the ST series and it has a max flow rate of 0.5 gpm (1.9 lpm). The ST Series is typically used for chemical metering applications.

Features

  • Efficient Pumping Action - One hose compression per revolution extends hose life
  • Low Maintenance - No valves, seals or glands
  • Reversible - Pumps can be used to empty lines or clear blockages
  • Extended Hose Life - Only one hose compression per revolution

Graco SoloTech Hose Design

With only the hose in contact with the fluid being pump and no check valves in line, Graco’s SoloTech peristaltic pumps are ideal for materials that other pumps cannot handle. Abrasive, corrosive, shear sensitive, and gas entrapped fluids can easily be pumped or dosed into your application.
