We make exact replacement pumps & spares from the Stothert & Pitt drawings as well as a comprehensive range of standard twin screw pumps. PERFORMANCE Capacity Range: 10-400 m³/hr - standard Pressures: Up to 50 bars range 400-1200m³/hr contact sales office for availability Viscosity: 1-60,000 centistokes Temperature: to 260ºC Low NPSH design: NPSHR is dependent on viscosity and speed and can be as low as 0.5M. CONSTRUCTION POINTS No screw contact by the use of timing gears Shaft stiffness maximised by the screw design Hydraulic balance ? Heated body and or covers ? Cooled bearings and or gearcases ? Vertical models save space DRIVES 2 or 4 pole motor speeds for normal duties. Diesel or gearbox drives for high viscosity or critical shear applications MATERIALS All irons, steels, bronzes and stainless steels including Nace and duplex stainless steel. ? Heating by oil, steam, or electricity ? With or without relief valve ? API 676 compliant FEATURES APPLICATION GUIDE: Albany twin screw pumps are used in a wide range of industrial, marine and offshore applications. These include:- INDUSTRIAL, OIL EXPLORATION & PETROCHEMICAL Aircraft refuelling Fuel Oil Boiler firing Railcar loading Railcar discharge Crude oil gathering Lubricating Oil Vegetable Oil Bitumen Slops Chocolate Fuel handling (high & low pressure) MARINE, OFFSHORE AND DOCKS Lubricating Oil Fuel Oil, to 70 bars Cargo pumping: Crude oil & oil products Slops Stripping Oily water Sea water, bilge & ballast Fresh water Fire foam concentrate Sludge Further models: From the Stothert & Pitt ranges: Internal Lobe pumps with capacities over 350 m³/hr Vertical & horizontal centrifugal pumps to 200m³/hr capacity From the Albany pump ranges: Gear pumps covering 1 to 2000 l/m on a wide range of liquids and in most materials.
