Q=0.5-300 m³/h (2.2 USGPM – 1321 USGPM)
P=0~2.4 Mpa (0~348 psi)
What is a
direct-coupled progressing cavity pump in industrial design ?
Direct-connected progressive cavity pump has no bearing seat, and the prime Mover bears the axial force of the progressive cavity pump, connecting the driving end and the flange at the end of the pump into a whole.
Its structure is compact and its axial dimension is short. Low investment, use and maintenance costs.
It is mainly used in environmental protection technology, food and chemical industries, etc., and can also meet various pressures of the petroleum industry, with stable delivery or precise administration.
