Pakistan 240m Diesel Engine Generator Horizontal Multistage
Dewatering Wter Centrifugal pump
Pakistan customer inquired four types firstly, who works in a
Mining Company in Pakistan. He would like to quote:
1. SS 904L 415v or 660v 100m3/hr 240m water submersible pump;
2. SS 904L 415v or 660v 160m3/hr 240m water submersible pump;
3. SS 316L 415v 280m3/hr 240m horizontal surface mounted multistage
centrifugal pump;
4. SS 316L 415v 100m3/hr 240m horizontal surface mounted multistage
centrifugal pump;
5. Spare parts including flow sleeves, PT100, Pressure sensor /
Gauge, Auto shutdown sensor due to temperature and water level,
Electromagnetic Flow meter and VFD.
All is for a bidder with respect to their requirement for supply of
submersible and horizontal multistage surface dewatering
centrifugal pumps.
In order to submitting the exactly technical and commercial offer,
we confirmed some details again as below:
1. For the centrifugal pump, is the diesel engine belongs to our
supply scope? Is there any special requirements on the diesel
engine brand? Usually, we suggest WEICHAI brand.
2. For the centrifugal pump, we think the NPSH 15m is not right, 5m
is available.
3.For the centrifugal pump, we found the NPSH marked on the
nameplate also is 5m, not 15m.
4. To be honest, NPSH 15m is impossible for any surface kind
centrifugal pump.
5. For the diesel engine, we think maybe it's diesel generator, it
will provide electric power to the pump?
Finally, we made a formal offer asap according to Pakistan
customer’s feedback.
