Internal gear pump
Technical support
Fluid-o-Tech IG series positive displacement internal gear pumps are designed to work in harsh environments, with unfiltered, abrasive fluids and in a wide temperature and viscosity range.

Therefore they are an excellent answer for the most demanding applications.
Flow rates are directly proportional to motor speed and pumps are reversible.
The housing is in cast iron whereas the internal parts are available in several options and materials to meet specific application needs.

Competitive advantages
Overview

Internal gear pumps are a positive displacement technology, very well suited for harsh environments. This technology will provide robust performance, low pulsation, good life, predictable and variable flowrate.

Advantages

Excellent for lubrication and recirculation

Repeatable and predictable flowrate

Reversible

High differential pressure capability

Excellent suction capabilities

Able to handle abrasive fluids with solid particles in suspension

Performs well with high temperature and viscosity
