The Muncie W Series hydraulic pump, part number W21-02AJ0-GTGT- or W2102AJ0GTGT, is the W21 displacement variant in Muncie's W Series gear pump line. This unit delivers a displacement of 4.87 in³ (79.8 cc) with a maximum operating pressure of 3000 PSI (210 BAR) and a maximum speed of 2500 RPM. The minimum operating speed is 600 RPM. Standard porting is the bi-rotational, 4-port design using SAE straight thread only, with -20 side and rear port sizing. Other porting configurations are available. Eight displacement options exist across the W Series. Motor applications require a case drain plumbed directly back to the reservoir. Call us to confirm proper fit for your application.
