Update to the hydraulic motor tank ports for HM1C, HM2C, HM3C, HM4C & HM5C Motors
Date: November, 2009
To: Hypro hydraulic driven centrifugal and hydraulic driven plunger pump customers
The hydraulic driven centrifugal pump and hydraulic driven plunger pump lines from Hypro have
long been a top performer in the field. As part of our commitment to quality and continuous
improvement, Hypro is providing notification of upcoming changes and recommendations to our
standard hydraulic motor line tank port and return line. This change will not affect product cost
and will be implemented across the standard Hypro hydraulic motor line on product
manufactured beginning January 1, 2010.
Update: Change from ½" NPT outlet tank port adaptors to ¾" NPT outlet tank port adaptors
Benefits: Provides a visual identification of pressure and tank ports reducing the likelihood
of reverse hook-up
Update: Tanks return line recommendation changes from ½" return hose to ¾" return hose
Benefits: Reduces internal motor pressures resulting in increased performance, reduced
seal pressures, and increased motor life.
