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.
