ZEILFELDER PUMPS

Positive Displacement Pumps

Zeilfelder pumps work by using two rotating elements, unmeshing at the suction side of the pump, to create a vacuum that fills the spaces created between the elements and the suction casing. These spaces then transport the fluid along the outer casing to the discharge side where the gears re-mesh and discharge the fluid.

Positive displacement pumps are designed to handle large changes in pressure, viscosity and flow rate and are often used for highly viscous liquids with large percentages of solids.

EXTERNAL GEAR PUMPS

High performance gear pumps

With our diverse standard and high performance gear pump range we are able to serve all your needs and respond to any challenge. Our external gear pumps are robust, self-priming, high quality and are designed for your specific application.

On demand, we can provide external gear pumps which API, ATEX,TR-CU 10, TR-CU 12 and TA Luft compliant

Pressure: up to 120 bar
Viscosity: up to 150.000 mPas
Flow rates: up to 5.000 l/min (300 m³/h)
Suction lift: up to 6 m
Temperature: -60 to 450°C

INTERNAL GEAR PUMPS

Standard gear pumps

Self-priming, non-pulsating and reversible pumps that work best on clean, lubricating fluids with a viscosity thicker than water. The internal gear pump is the low cost variant within the gear pump range.

On demand, we can provide internal gear pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant
