Heavy Oil / Positive Displacement Pump / Explosion Proof / Abrasive
And Aggressive
A Tank Cleaning Company needed a durable Positive Displacement
Pump: Oil with a viscosity of 300-380 cst is sprayed through
nozzles as a protective layer on tank walls to prevent corrosion. A
Accuvon Rotary Lobe Pump with Diesel engine was chosen because of
its robust and maintenance friendly design.

Production processes in the oil industry depend heavily on robust
and durable pumping systems. The wide range of pump sizes, the
option loaded modular design and the peripheral equipment enable
Accuvon to supply a suitable Rotary Lobe Pump for your oil
application. Accuvon Rotary Lobe Pumps are manufactured to the
Explosion Proof Standard.
The Accuvon MIP-Design is a unique advantage to minimize downtime
and maintenance: MIP (Maintenance In Place) allows the quick and
convenient replacement of all fluid wetted parts without removal of
pipes, drives or other components of the pump unit by your own
staff. Quick - Uncomplicated - Inexpensive.
Petrochemical fluids often include abrasive and aggressive
characteristics. Wide viscosity ranges demand customized solutions
for pumping systems: Accuvon offers rotor materials with different
coatings (Elastomer, PTFE or Urethane) or solid stainless steel
rotors. Casing protection plates are supplied with different steel,
plastic or ceramic quali[1]ties. For operational safety the Accuvon
relief valve can be added as a mechanical over pressure protection
device.
Variety of Rotor Designs Rotor geometry and materials are
customized for each individual application Rubber elastomers,
Urethane or stainless steel lobe designs are available.
Similar application of sewage treatment:
Accuvon provides many applications on-board ships and in other
areas of the marine industries - from handling of both fresh and
seawaters to fuels of all kinds, oil or oil sludge, bilge or other
water-oil mixtures, fish or fish waste, sewage or other fluids with
or without solids, of low or high viscosities.
Sewage | Ballast Water | Bilge / Loading | Oil Sludge | Fuel /
Crude Oil | Oil-Water Separation | Fish / Kitchen Waste | Mud |
Emulsions | Oilfield Chemicals | Marine Diesel Oil | as Skimmer
