Bulk liquid transfer pumps utilizing two contra rotating screws providing a smooth pulse free flow. Each screw is accurately located between bearings providing a physical gap between each screw and between the screw set and casing, thus providing a positive displacement pump, which does not require internal lubrication from the pumped liquid.

Pumps are available with a sensitive dashpot relief valve for rapid opening and damped closing and can be fitted with relief valve jacking device for manual by pass/re-circulation of liquid.

There are five sizes available (W40, W80, W125, W225, W375) with the number indicating the nominal flow in M3/hr.

These pumps are available in Horizontal & vertical arrangement with inboard as well as out board configuration.

Pumps constructed from stock materials (Iron and steel) are commonly Used for:

• Lubricating oils.
• Fuel Oils (residual and distillate)
• Petroleum liquids
• Bitumen / Asphalts
• Solvents
• Vegetable oils
• Glues, varnish, resins, paint, polymers
• Custom-built pumps - typically in stainless steels or bronze are used for applications with mild corrosion effect, such as Palm oils, Fatty acids, Water (fresh or sea), and Some acids.
  

Any bulk transfer of liquid - such as:

• Rail/road car unloading / loading.
• Tank to tank transfer. (and process to tank transfer).
• Ships bunkering.
• Ships liquid cargo pumping.
• Bilge and ballast pumping.
• Distribution in liquid marketing terminals.
• Pipeline and process flow requirements.
