Marlow Series 20EVP Self-Priming Pumps
Marlow Pumps
Marlow Vertical In-Line Self-Priming Centrifugal Pumps for Petroleum’s and Solvents
Pump: Heavy-duty cast iron construction, with 2" NPT female threaded in-line suction and discharge ports. This compact, vertical design is self-supporting and requires a minimum of floor space. The self-priming feature allows the pump to be mounted above the liquid and suction lifts of 10' to 20' can be achieved, depending on the liquid and the pump model. Diffuser priming eliminates the need for a check valve and reduces radial loads insuring longer bearing life. These pumps are sealed by a self-lubricating, Viton mechanical shaft seal. When used on a suction lift any leakage that may occur will be down into the pump rather than up the motor shaft as the seal is on the suction side of the impeller.
Motor: Single phase motors are 60 cycles, 115/230 volt, except 2 HP explosion proof motors which are 230 volt only. Three phase motors are 60 cycles, 230/460 volt and all are 3450 RPM motors. All explosion proof motors are Class I, Group D, Code: T3B.
Optional Mounting: All models fit the Marlow Pumps lightweight, two wheel chassis.
Optional Seal: Kalrez mechanical seals are available.
