Hi,fiends
Currently we receive from a provider a screw pump ALLWEILER manufacturing lubrication associated with a pump of the coker. The pump is attached directly to the shaft of the pump of the coker. The problem is that pump we receive works in the opposite direction CW when really should operate in CCW direction.
Can I install this pump by turning in the opposite direction with the solution exchange the suction and discharge lines?
There any problems in pressure or discharge by turning in the opposite direction?
Their recommendation will be well received
Thanks...

Shaft driven pumps like this may have a suction check valve or foot valve so that the pump retains prime. The suction line does not have PSV protection. If you run the pump in reverse, you could burst the suction line. We had this happen once when a pump was accidentally puchased for the incorrect rotation.
