Economic and easy for operation
The wetted parts are made of PTFE and FEP with compact structure, easily for operation, competitive price.
Pump parts are interchangeable for coupling type and close coupling type pump
The pump casings, impellers, and mechanical seals of FSB/FSB (D) are interchangeable.
Impeller, mechanical seal and shaft are integrity, the torque transferred by morse taper shaft, and the shaft sealed by WB2 mechanical seal.
Grease – lubricated bearing, the bearing box needed to filled in engine oil.
