Gear Pumps

Internal & External Gear Pumps For a Wide Range of Applications

Our ranges of internal 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 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 choice for your application. Talk to Michael Smith Engineers today about your requirements.
