Screw Pump

The new Aqua Guard screw pump boasts high performance with extremely viscous fluids

The NEW positive displacement screw pumps boast high performance with light and extremely viscous fluids. The pumps are ideal for oil skimming systems, emergency transfer, bilge pumping, offloading and ballasting.

The pumps have been performance tested at Ohmsett (The National Oil Spill Response Research & Renewable Energy Test Facility, USA).

• Archimedes’ screw pump with sealing disc
• Positive displacement
• High capacities from 19.2m3/h to 35.6 m3/h (121 to 224 bbl/h)
• High delivery pressures from 10 to 14 bar (145 to 203 psi)
• Fully manufactured in stainless steel AISI-316
• Minimum manhole diameter from 300 mm to 350 mm (11.8 to 13.8 in)
• 50 to 75mm (2 to 3 in) camlock discharge port
• Solids handling from 15mm to 25mm (0.6 to 1.0 in)

• Can be run dry or with water (ideal for OSR training)
• Compact and robust
• Chemical and corrosion resistant
• Easy disassembled, cleaned and maintained
• Fluid viscosity - water to heavy oils
• Does not emulsify oil

Currently, a higher capacity pump is in development which will be ready early 2020.
