Oil / Solvents / Unloading Of Tanker / Wide Viscosity Ranges /
Rotary Pumps
A refinery with tank terminal uses Accuvon Rotary Lobe Pumps for
unloading of tankers. A complex pipe system and a wide variety of
viscosities often create pressures up to 10 bar (145 psi). For
additional support the pumps are equipped AF – Quick Release
Covers.

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.
