Attached is a screw pump with a motor coupled on the side. The pump shows the direction it should run,but that will require motor to run anticlockwise and does not pump. lt only pumps when the motor runs clockwise and the pump running wrong direction.
Hi,
Check the manual and or ring the manufacturer.
Why will it be different from the past, your pump has been running for quite a while?
Weird to me.

10. ROTATION The M-Range of Industrial pumps is suitable for rotation in either direction, i.e. flow direction out either of the pump flanges. The bearing housing direction plate indicates the resultant flow path dependent on mainshaft rotation direction. Pump flow curves also indicate flow direction. NOTE: It is recommended product flow is directed out the “end cover” (opposite drive end) side of the pump in applications where: • Pressure above 10 bar is required (dependant on pump capabilities) • No suction lift is required. For Suction lift applications, delivery must be on gland.

Thank you sir, so for attached set up, the rotation should be the one shown on pump name plate(shown as red arrow)? And can we say we have suction lift here?

Hi Pierreick,
we modified the pump currently so as to have suction on the drive side. The pump is pump is working perfectly fine, as we tried the direction as per nameplate, but it didnt pump. We then reversed the pump direction and it didnt pump. So l am just questioning why it only pumps when we run it opposite to manufacture's guideline. Thanks
