MP SERIES -- PUMP SPECIFICATIONS
* Intermittent rating of 140 Bar
Consult the factory for special requirements that must be met if the
pump is to operate beyond one or more of the limits specied above.
Horsepower Ratings:
We recommend a 1.15 service factor be specied when selecting an electric motor as the power source.
To compute electric motor horsepower required, use the following formula: HP = (GPM X PSI) / 1450.
The formula to determine the horsepower required for a gas engine is: HP = (GPM X PSI) / 1150.
The formula to determine the horsepower required for a diesel engine is: HP = (GPM X PSI) / 1250.
For the Application of a Hydraulic Motor:
To Determine the Torque of a Hydraulic Motor -- (GPM x PSI x 36.77) / RPM = Torque (in-lbs)
Calculating RPM / GPM of Pump:
A pump must be connected to an electric motor or gas or diesel engine with the correct ratio of pulleys
and belts to attain the required speed and GPM. The use of a Variable Frequency Drive (VFD) may also
be used to control the RPM of a properly sized electric motor when variable ows are required.
(Max. Pump RPM / Rated Pump GPM) x Required Pump GPM = Required Pump RPM
To calculate a pulley diameter one (1) pulley diameter and the required pump RPM must be known:
(Pump RPM x Pump Pulley Diameter) / Motor RPM = Motor Pulley Diameter
(Motor RPM x Motor Pulley Diameter) / Pump RPM = Pump Pulley Diameter
