  3 Questions
Q: can you run hot water through theTS2021?
by Marco M from New Mexico on April 27, 2014

A: The MAX water inlet Temperature for this pump is 165 Degrees.
by Brian, Product Expert
Q: Can the TS2021 pump have a direct mounting flange attached to it.
by Mike on March 02, 2012

A: This pump has a 24mm solid shaft and primarily it is always a pulley driven pump, however there is a gear box available that can be mounted in between it and a gas engine so it can be direct mounted. There is also a flange and coupler to mount this to an electric motor. So if you needed to direct mount it, technically it can.

The parts needed to directly mount this pump would be an additional cost.

Q: Bill what size electric moter would I need to run the model TS2021 pump.
by Mike on March 02, 2012

A: You would need approximately a 12-13 horsepower electric motor to operate this pump. If you click on the specs tab for this product, you will see an owner's manual link to the right. Click on that owner's manual link and check out page 4. You will see a chart that shows the requirements for the GP pumps.
