Crown 120 Triplex Mud Pump

< Back

Crown 120 and Crown 737 are an underground industrial standard known for their mud pumping abilities with SG’s of up to 1.2. The high flow (up to 44m3/hr) and high pressures (up to 225 Bar) achievable on these pumps are what make them perfect for underground mine mud transfer as well as sewage plant sludge movement. These pumps are also extensively used in steel mill plate descaling, mud drilling and for pumping light tar’s and resins within the petro-chemical industry. Materials of construction include fabricated steel casings with bronze crosshead wear liners, nodular iron eccentric and connecting rods transferring the fluid via steel, thermally coated plungers through forged steel fluid ends. Eccentric drive is via heat treated jackshaft pinions on eccentric ring gears. The pumps recommended slow eccentric speed (120 rpm) ensures pump reliability and wear component longevity.
