TRANSCRIPT
Robust design provides solid foundation for trouble free operation. Availablein Cast lron, Ductile lron, Cast Steel or Stainless Steel with minimumcasing working pressure of 40 kg/cm2(580 PSIG).
Precision casting stainless steel impeller is standard on all ACME MVDpumps. They are keyed to shaft for positive drive and offer high efficiency.
MVD pumps are provided with diffusers to ensure that radial load isminimized when the pumps are operated at reduced flow.
Hydraulic balancing is achieved by balancing drum. This reduces theaxial load on the bearing to a minimum and increases the bearing life.
MVD pumps are fitted with angular contact grease lubricated ball bearingas standard. Oil lubricated bearings are available as an option.
The radial bearings are available in coke filled TFE, Silicon Carbide orTungstun Carbide. They offer the highest mean time between pumpmaintenance and reduce operation cost.
The radial bearing is mounted on a removable housing for ease ofmaintenance without removing other parts of the pump.
Available in high tensile steel, 416 Stainless Steel or Duplex StainlessSteel with replaceable sleeve to minimize maintenance cost.
The stuffing box can be provided with packing or mechanical seals. Whenmechanical seals are used, they can be replaced without dismantling thepump.
MVD pumps can be fitted with multiple outlets that enable users to tapdifferent discharge pressure to meet the system requirement with singlepump installation.
Multiple Outlet
Description
ACME MVD MULTISTAGE VERTICAL DONUT PUMPS are designed for water transfer, fire protection,pressure boosting, boiler feed and other applications where noise and vibration must be kept to aminimum.
It is a low flow, high-pressure pump that offers users high efficiency, reliability at low cost. It alsorequires less installation space and provides piping flexibility and ease of maintenance.
