PD 201 — High Pressure Helical Gear Pump

PD 201, using the same housing structure as PD 200, consists of a high pressure series helical gear pump with R 2½" / DN65 PN16 connection. With a fixed flow capacity of 25 m³/h (~417 lpm), it provides pulsation-free and reliable flow in the pressure range of 8 to 12 bar. Operating at 1000 rpm; the pump meets demanding high pressure processes with motor power of 15 kW for 8 bar, 18.5 kW for 10 bar, and 20 kW for 12 bar. Complementing PD 200's low-to-mid pressure (2–6 bar) applications, PD 201 is designed for lines where higher system pressures are required with the same flow demand. The common housing structure greatly simplifies spare parts and service processes between the two models. The helical gear mechanism, offering stable performance across a wide viscosity range (220 cst reference); is an ideal choice for high pressure transfer lines in the chemical, petrochemical, shipbuilding, and paint-ink sectors. Housing material, shaft sealing, and gear options can be customized according to process requirements.
