GEAR PUMPS internal / external

The HPI Series of External Gear Pumps is our most economical solution to date. This Series HPI is a standard of the shelf product for standard applications. Internal Gear Pumps are self-priming, non-pulsating and reversible pumps that work best on clean, lubricating fluids with a viscosity thicker than water. Two gear teeth, one idler and one driver, mesh together around a crescent divider to transfer the liquid. Because of the simple one shaft construction, Internal Gear Pumps are less expensive than comparable pumps and are very easy to maintain.

Performance Data:

• Pressure: standard 200 psi (14 bar) (higher pressures go to different series)

• Efficiency: to 90%

• Viscosity: 1 to 55,000 cst (mPas) (higher viscosity upon request)

• Flow rates: 0.037 gpm - 603 gpm (10 up to 4,120 l/min)

• Speed: up to 1400 rpm

• Suction lift: up to 12 ft (4 m)

• Temperature: -40°F to 572°F (-40°C to 300°C)

• Materials: standard materials

• Seals: lip seals, packing, single or double mechanical seals, magnetic coupling

Our standard high process efficiency, high performance gear pumps are able to serve all your process applications. Our gear pumps are reliable, heavy duty, self-priming and can be adapted to your specific application. External Gear Pumps are self-priming, non-pulsating and reversible pumps that work best on clean, lubricating fluids with a viscosity thicker than water. Two gear teeth, one idler and one driver, mesh together to transfer the liquid. Because of the balanced construction and bearings on both sides of the shafts, the pumps are capable of non-pulsating flow and high pressures. We can provide External Gear Pumps compliant with API, ATEX, TR-CU 10, TR-CU 12 and TA Luft.

Performance Data:

• Pressure: standard 360 psi (25 bar) (optional up to 1760 psi (120 bar))

• Efficiency: 60 to 92%

• Viscosity: 0,5 to 25.000 cst (mPas) (higher viscosity upon request)

• Flow rates: 0.11 gpm - 79 gpm (0,4 up to 300 l/min)

• Speed: up to 3000 rpm

• Suction lift: up to 19 ft (6 m)

• Temperature: -76°F to 840°F (-60°C to 450°C)

• Materials: all available materials

• Seals: lip seals, packing, single or double mechanical seals, magnetic coupling
