Gravel Pump Performance Parameter Range

Feb 06, 2026 Leave a message

Flow: 36–5040 m³/h (some models can reach 5040)

 

Head: 5–90 m

 

Power: 60–1200 kW

 

Speed: Commonly 720, 990, 1480, 2960 r/min

 

NPSH (Net Positive Suction Head Required): 1.5–6 m, good anti-cavitation performance

 

Sealing and Transmission Methods

Shaft Seal Types:
Packing seal (suitable for suction lift or backflow conditions, requires shaft seal water)


Auxiliary impeller seal (suitable for backflow conditions, does not dilute slurry but increases shaft power by about 5%)


Mechanical seal (good sealing effect but high cost)

 

Transmission Methods:
V-belt drive


Elastic coupling drive


Gear reducer, hydraulic coupling, variable frequency drive, SCR speed control, etc.
