Our ranges of internal gear pumps and external gear pumps cover capacities from microlitres per hour to 345 m3/hr. Maximum discharge pressures between 8.7 Bar and 150 Bar can be covered, depending on the duty required and the pumped liquid's characteristics. All our gear pumps give smooth pulse-less accurate positive displacement pumping over a wide range of temperatures and viscosities, from thin liquids to high viscosity liquids. With a choice of wetted materials and shaft sealing options, we are able to offer you the right gear pump for your application.
