BÖRGER GmbH is presenting in addition to its range of Rotary-lobe pumps a new design of a macerator

19.06.2002

The BOERGER – UNIHACKER is a disintegrating device for raw sewage and sludge.

It contains of 2 rotating shafts, which are operating in different speeds.

The design is unique and patented in that way that the basic construction of the UNI-HACKER is identical with the Rotary-Lobe Pump design. The cutters and spacers are from heat-treated, hardened alloy steel.

The front cover design allows also a quick access to the cutting chamber, by removing of 4 screws only. The maintenance can be done in place.

The difference between both systems is, that the shafts are operating at different speeds, while with a pump they have to operate synchronic, and despite to the installation of the

Lobes into the pump-unit, there will be cutters and spacer installed instead.

The advantage of this design is that the majority of parts are identical between pump and macerator. Especially if you see the combination of both together, it will allow a interchange ability of parts between both systems.

Unlike existing systems of macerators on the market, the UNI-HACKER has wear-plates to protect the casing from the chance of wear.

From that reason the UNI-HACKER fulfils also the requirements for the MIP-design, introduced for the BOERGER Rotary-Lobe Pumps 2 years ago.

MIP stand for “Maintenance in Place”. This means all of the wear parts (Rotors or Cutters, sealings and wear-plates) of the cutters as well as the pumps can be replaced without and disassembling of the pump or disassembling of the pump from the pipe system.

In addition to the UNI-HACKER, BOERGER is presenting during the PSA exhibition its full range of Rotary-Lobe Pumps and Gear pumps from 0.5 – 900 m3/h.

Please visit company during the PSA in Singapore from 9th – 12th July in Hall 3 at booth 3313, visit the website at http://www.boerger-pumps.com, or contact the local office.

BRAND-NEW

As a brand new development, BOERGER present its new Internal gear pump during the PSA 2002 in Singapore

The BOERGER Internal-Gear Pumps are self-priming, valve-less positive displacement pumps. The operating principle is identical to a typical internal gear pump.

However not the idler is the driving part; in this case the impeller is driven by the shaft. That allows an easier construction without bushings and a simplified maintenance. This design is patented in many countries.

Internal-Gear Pumps are well suitable for a pulsation-free, continuous and adjustable flow, for mixing and dosing applications; of thin to high viscous liquids. The pumps are currently available from 0.1 – 100 l/min with pressures up to 10 bar. A wide choice of materials allows installations a various industries.

Multi screw pump moves highly viscous heavy oil at low NPSHa

22.02.2024 -

At a tank farm in a Brazilian sea port, two centrifugal pumps were used for transferring heavy oil from storage tanks to road tankers or vessels until February 2020. This required the high viscosity of the medium to be reduced by means of diesel injection, costing the owner at least 2,000 US dollars each day. In addition, the centrifugal pumps regularly broke down due to cavitation damage. The owners decided to initially replace one of the two centrifugal pumps with a NOTOS multi screw pump from NETZSCH. Due to its very good suction capabilities, the selected four-screw 4NS is also suitable for highly viscous media with up to 200,000 cSt, achieving a flow rate of up to 3000 m³/h.
