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.
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.
