Submersible pumps type for Lift stations of various waste water ( chemically contaminated )

Submersible pumps type for Lift stations of various waste water ( chemically contaminated )

Submersible pumps type for Lift stations of various waste water ( chemically contaminated )

(OP)
Contractor requests to go for VS4 type vertical submersible pump instead of earlier proposal of Submersible pump as the zone classification of these lift stations are now considered to be one 2. They say that submersible pump motors cannot be made suitable for Hazardous zone.

Is it agreeable to accept the contractor proposal so that the motor is complied with the required classification?

Thanks in advance for your reply

RE: Submersible pumps type for Lift stations of various waste water ( chemically contaminated )

Not sure why the Contractor would make such a statement as one can procure explosion proof submersible pumps.

However, you have not provided enough details on your application to understand it. What is the application, pump size, pumping conditions, chemicals, etc.

You should be aware that submersibles have higher maintenance requirements than other pump types.

vjr0512, you already have the exact same question in Pump Engineering with 14 replies to date, double posting is not encouraged and you should ask management to delete this post, before someone else does.
