Bornemann - Twin-Screw Pumps, Progressive Cavity Pumps and Multiphase Pumps

Bornemann was established in 1853 and has been designing and constructing pumps and pump systems for over 75 years.

In 1934, Bornemann began designing and manufacturing twin-screw pumps with external bearings, which today are still the foundation of our production and the premier pumps of our product line. This was followed in 1960 by the triple-screw pump, and in 1966 by the progressive-cavity pump, and finally in 1985 by the multiphase-pump.

Bornemann pumps have diverse and practically unlimited fields of application: waste oil pumps for tanker vehicles, ink pumps for printing ink, waste water pumps in sewage plants, seepage pumps at waste depositories, cement grouting and concreting pumps in the construction industry etc.

Bornemann twin-screw pumps are self-priming, double ended positive displacement pumps with external timing gears and bearings. Manufactured in over 80 sizes, their design provides complete axial balancing of the rotating elements and eliminates all metal-to-metal contact within the pump.

They can handle virtually any non-homogeneous fluid, regardless of viscosity, lubricity or abrasiveness e. g. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.

W/V SERIES TWIN SCREW PUMPS

These pumps can handle virtually any fluid, regardless of viscosity, lubricity or abrasiveness e.g. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.

The W-range is a horizontal pump execution with external bearings. We distinguish from the short execution (Wzk) and the long pump execution (Wz). The short execution will be used for applications with high differential pressures. Due to the low space for the mechanical seals the choice of the seals is limited.

HP SERIES TWIN-SCREW PUMPS

The Bornemann HP-type series pump was developed specifically for high-pressure crude oil (including oil, water, wax and even a minor gas content) transfer applications. The heavy duty design has proven its superior performance in various applications and countries over the last 25 years.

HC/VHC SERIES TWIN-SCREW PUMPS

This two-piece design pump allows the screws and shafts to be replaced independently of one another, maximizing interchangeability while reducing maintenance cost and downtime. Shafts are made of high-quality stainless steel (DIN rating 1.4542, ANSI 630 S.S.) as standard equipment.

The screws can be supplied in a wide range of materials including cast iron, nodular iron, bronze, and various stainless steel grades - allowing numerous different material combinations to best fit the particular application at hand. For the pump casing there are various materials available including cast iron, nodular iron, or cast steel.

SL SERIES TWIN-SCREW PUMPS

The pumped fluid flows through the screws in an axial direction. Therefore, the pump imparts very low shear and little pulsation to viscous and shear-sensitive products. For this reason, SL pumps are well suited for fluids with high or low viscosity, with lubricating or non-lubricating properties, and fluids containing some solids.

The SL pump can easily be adapted to the user's requirements according to viscosity, temperatures, working pressure, speed and other criteria. Speeds range from 200rpm up to 3,600rpm.

MW AND MPS SERIES MULTIPHASE BOOSTING PUMPS

Multiphase boosting pumps are widely used in old onshore fields with low wellhead pressures, new onshore field developments with high viscous crude oil, steam injected fields, and for the replacement of conventional separation technology onshore.

PROGRESSIVE CAVITY PUMPS

The Bornemann progressive cavity pumps consist of only one basic moving part - a driven metal (inelastic) rotor rotating within an elastomer lined (elastic) stator. As the rotor turns, chambers are formed between the rotor and stator. These chambers progress axially from the suction to discharge end, moving the fluid. By increasing the pitch of the rotor and stator, additional chambers, or stages, are formed.

As the number of stages increases, the pressure capability of the pump increases proportionately. This design permits pumping in either direction and provides the high suction lift capability and smooth, pulsation-free delivery for which Bornemann pumps are known.

Available in numerous rotor / stator material combinations, their ability to handle fluids gently and with extremely low shearing makes the progressive cavity pump ideally suited for metering and dosing services.
