Shop All Gear Pumps
A gear pump moves viscous liquids such as oils, resins and syrups by carrying fluid between meshing gear teeth; internal gear designs run quieter and self-prime better than external gear. DWP has a Rotan HD66EM-1U3B2 2.5 inch internal gear pump listed here and a Flowserve E3-INT-GEAREX rotary gear pump under the main pump collection.
Gear pumps come through in small numbers, so request a quote with the size, flow, viscosity, seal type and material and we will source a Viking, Tuthill or Rotan unit to match, usually with pricing in 24 to 48 hours. The 30-day money-back guarantee applies.
