We carry the following Permco Series Numbers for Roller Bearing Pumps:  P2100, P2500, P3000/3100, P5000/P5100, P5151, and P7500/7600. Click on the 'details' button to see a list of specifications for each series.

Sump strainers are used in hydraulic fluids, coolants, lubricants, and many process fluids.  All have strong perforated metal support tubes under the straining elements.  All are available with optional, built-in bypass relief valves to avoid starving the pump should the strainer become dirt clogged.

The D9 Series of motor is the largest member of the White Drive Product's family.  The product is capable of producing torque values comparable to competitive motors, but with an industry leading breadth of displacements and shaft and porting options.  In addition, the product incorporates dual tapered roller bearings, which improve load carrying capabilities.  The motor is designed for use with a case-drain, which reduces pressure on the shaft seal and maintains lubrication to internal drive components, maximizing motor life.  The series is available with industry standard mounting flanges found throughout the global market place.

Due to its case drain design, the DR Series motor is an excellent size motor for applications with high-duty cycles or frequent direction reversal.  The case drain design produces a number of benefits including reduction of pressure on the shaft seal and the ability to provide a cooling loop for the system.  The case flow also lubricates the vital drive components, extending motor life.  An internal drain option is also available.    A laminated manifold and three-zone orbiting valve are used to produce higher overall efficiencies and more usable power.  A steel faced seal in the orbiting valve also reduces the risk of the seal extruding or melting, which is possible in competitive designs.

The HB Series motor is the leader in its class, offering high efficiency and durability.  The three-zone orbiting valve, laminated manifold and Roller Stator® motor work harmoniously to produce high overall efficiencies over a wide range of operating conditions.  The standard case drain increases shaft seal life by reducing internal pressures experienced by the seal.  Case oil leakage is also directed across all driveline components, increasing motor life.  An internal drain option is also available.  At the heart of the motor is a heavy-duty drivelink, offering 30% more torque capacity than competitive designs.  These features make the HB Series motor the preferred choice for applications requiring peak efficiency for continuous operation.

RE Series motors offer the perfect compromise between price and performance by producing work horse power at a reasonable cost.  Although these motors perform well in a wide range of applications, they are especially suited for low flow, high pressure applications.  During startup, pressure causes the balance plate to flex toward the rotor, vastly improving volumetric efficiency.  As the motor reaches operating pressure, the balance plate relaxes, allowing the rotor to turn freely which translates into higher mechanical efficiences.  Transmitting this power to the output shaft is the most durable drive link in its class. Four bearing options, combined with standard mounting flanges and output shafts, allow the motor to be configured to suit nearly any application.

RS Series mtors are the most economical model in the White Drive Products product line, but are not low-tech.  Unlike competitive products using power robbing, two-piece rotor set designs with sliding contact points, RS Series motors utilize the patented Roller Stator® design.  Seven precision rollers for the contact points reduce friction, providing more power and longer life for your application.  Each output shaft is custom ground to maintain exact tolerances between the housing and shaft, producing high volumetric efficiencies.  Industry standard mounting flanges and output shafts allow the RS Series motors to interchange with competitive designs. 

The WS product family featuares flow rates up to 76 LPM (20 GPM), torque up to 824 Nm (7,925 lb-in), and pressures up to 207 bar (3000 psi) at continuous ratings.  The WS targets agricultural equipment, skid steer attachments, and other applications that require greater torque under demanding conditions.  A distinguishing feature of the WS in relation to competitive products is its heavy duty drive link with a larger pitch diameter.  This enables the WS to to better withstand pressure and torque spikes and is reflected in its intermittent and peak performance ratings.  Additional product features include a three zone commutator valve, heavy-duty tapered roller bearings, and case drain with integral internal drain.
