Marlow Series 20EVP - Vertical In-Line Self-Priming Centrifugal Pumps
for Petroleums and Solvents
STANDARD UNIT INCLUDES:
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 cycle,
115/230 volt, except 2 HP explosion proof
motors which are 230 volt only. Three phase
motors are 60 cycle, 230/460 volt and all are
3450 RPM motors. All explosion proof motors

Marlow Pumps lightweight, two wheel chassis.
