Duplex Stainless Steel Multistage Centrifugal Diesel Dewatering Pump

Duplex Stainless Steel Multistage Centrifugal Diesel Dewatering Pump

Short introduction:
Its style conforms to ISO2858. Overflow components of the pump are created of 304,316,316L,Ti, ect. There is shaft coupling in the pump. For reparation, disassemble shaft coupling and there is no require to disassemble pipes or motor.

Overall performance:
Circulation potential: one.eight-400 m3/h, Carry: 15-125m, greatest temperature: 400ºC, stress 1.six MPa. 

To transfer natural chemical medium

With a suspension frame, there is no want for a cooling circumstance when transfer large temperature medium. Its running functionality is improved by hydraulic product, Hastelloy isolation cover, and polished Impeller passage.


Flow rate: Q= 2~2050 (m³/h)
Total head: H=3~150 (m)
Pump speed: n=1450/2900rpm
Design temperature: T=-20~150ºC
Fluid s.g.: γ≤1.eighty five
Pump diameter: 50~350mm


  1. Single stage,single suction,horizontal centrifugal pump. Bracket structure for bearing parts, the bearing housing is supported by the bracket. The axial displacement of pump rotor part can be adjusted by a special bolt. Closed impeller(ZBG type),semi-open impeller(ZBK type) and fully opened impeller(ZBQ type) are available.
  2. The impeller is connected with shaft by screw thread, an anti-vortex plate is adopted at the pump inlet to increase the reliability of pump.
  3. The impeller with rear blades is adopted to balance the axial force at the pump suction. And the gap between the rear blades of impeller and pump cover can be adjusted by a bolt.
  4. The pump structure is back pull type,the rotor part(impeller,shaft,shaft sealing and bearings) can be removed without dismantling the pipes during maintenance.
  5. The shaft sealing is cartridge mechanical seal, and can be customized as single mechanical seal, packing sealing and secondary impeller+packing sealing.
