Showing Questions of 6

Do you have the motor ( model no.: 40665D-L75-2 ) of the Hi-lo treatment table (John S. Barnes Corp.)? many thanks.

A: No. Any Barnes pumps or motors we have are strictly random surplus items and we do not have a complete range available.
Date Submitted: 07/28/2018

What horsepower is needed for this pump?

A: Minimum of 4 HP required for gas engine use
Date Submitted: 04/25/2018

Why does this pump have 3 ports in the picture?

A: Very little information was provided with this pump. What we know is listed. It appears to have been designed for a specific purpose which would need the separate outlet ports, but we have no information to clarify.
Date Submitted: 12/15/2017

What coupler is used for this pump?

A: We do not have a coupler to work with this pump. One would have to be manufactured, most likely.
Date Submitted: 04/10/2017

The rotation for this pump is looking at from the shaft side (front). correct?

A: Yes, we call out rotation as facing the shaft.
Date Submitted: 01/04/2017

Will a 3 hp 3600 rpm tefc motor run this at full psi?

A: No. While it may be possible to trigger the unloader with that HP if it's set low enough, the max pressure possible continuously at that flow with 3 HP is just over 1250 psi.
