CM Series Pumps—Drive Options
CM Series pumps are midship-mounted centrifugal pumps with multiple impellers. Depending on the model, pump capacity can range from 500 to 2,250 GPM
(1,900 to 8,550 LPM). CM and CMU pumps are available with direct drive or one of the following transmissions: C22 (rear- or front-mounted), K, or PA (rear-
mounted only). Direct drive applications are available with clockwise or counterclockwise rotation.

CM Series Pumps—Intake and Discharge Flanges
CM Series pumps are available with angle-compensated or non-angle-compensated front and side discharge flanges—pump without angle compensation shown
below. Pumps with angle compensation feature a front discharge flange angled at 4° and side discharge flanges with holes machined at a 4° rotation. This option
ensures that the discharges align with the operator panel after installation.
FeatureFeature DescriptionDescription
1Center discharge flange Water exits the pump through this discharge. In applications where discharge plumbing is not needed, a cover is available.
2Side discharge flange Water exits the pump through the side discharges. Optional discharge fittings and plumbing are available to connect to the
discharge flanges.
3Front discharge flange Water exits the pump through this discharge. In applications where discharge plumbing is not needed, a cover is available.
4 Intake flange Water enters the pump through the intakes. Optional intake fittings are available to connect to the intake flanges.
5Tank-to-pump flange This is where the tank-to-pump valve or fitting is mounted on the pump.
6Priming valve mounting pad This is where the priming valve is mounted on the pump. In applications without a priming valve, a cover is available.
