Overview

The Liquiflo H Series are positive displacement, external gear pumps designed for pumping low capacities of liquids at high differential pressures. The pumps are typically used for metering, circulation, transfer and injection applications. The pumps have been specially engineered to handle many difficult chemicals - such as polymers, solvents, acids, caustics or other corrosive liquids over a wide range of viscosity (0.3 to 100,000+ cP), pressure and temperature. Available in packed, mechanically sealed and leak-free magnet drive versions, the range consists of 12 models and covers flows up to 180 lpm and differential pressures up to 15.5 bar.

Liquiflo gear pumps are manufactured from high-alloy materials such as 316 Stainless Steel or Hastelloy Alloy-C, and a variety of corrosion-resistant and wear-resistant internal materials. Liquiflo gear pumps can be configured with packing, single or double mechanical seals, or magnetic-drive.

Liquiflo Gear Pumps are available with several ancillary options and accessories. These include temperature control jackets, gear reducers, variable speed drives, air motors, relief valves, repair kits, replacement cartridges and base plate mounting. All models are self-priming and available in close-coupled or long-coupled configurations. This close coupled option makes installation quick and easy, since it eliminates the need for manual alignment of the pump and motor, and pump lifetimes are significantly extended since perfect pump-motor alignment is guaranteed.
