Twin-screw spindle pumps
Bornemann spindle pumps with two spindles are rotary displacement compressor pumps; gearwheels and roller bearing lie beyond the pump space. About 80 construction variations are available. Different materials, overall sizes and construction forms allow fertilizer-optimised solutions.
Nearly all media can be promoted: Thin-liquid - as for example petrol, hydrocarbons and sea water - also liquids with the highest viscosity - like minerals, bitumens, glue, molasses and others - and also aggressive media - like acids or lyes
Optimised solution for every application, e.g., in the areas of
- oil support
- tank camps
- petrochemistry
- refinery
- marine
- offshore
- food production
- drink industry
Type Series W
twin-screw self-priming displacement compressor pump - outside-stored
 unique achievement width - conveyor amount proportionally to the speed
- high viscosity possible for almost all media
- low pulsation
- low sound level
- recorders dry run is possible
- conveyor amount nearly consistent at fluctuating pressure and viscosity
- very good suction up to NPSH 1 - 1.5 m
- available in more than 70 dimensions and in a huge number of materials
- conveyor streams from 2 m ³ / h to 2,000 m ³ / h and pressure to 50 bar
Type Series HC / VHC - compact version
twin-screw self-priming displacement compressor pump - outside-stored
- especially for tank loading and unloading
- big achievement width
- optimum relation conveyor screw / construction length
- high pressure-stiffness
- conveyor stream enlargement to 30% *
- increase of the efficiency to 15% *
- improved suction behaviour to 8.50 m*
- weight reduction to 35% *
- place savings to 30% *
- difference pressure to 16 bar, conveyor streams to 650 m ³ / h
- vertical and horizontal construction
* in comparison to standard
Type Series HP
twin-screw self-priming displacement compressor pump - outside-stored
- especially developed for pipelinie transfer
- extremely robust
 steady run - pulsation-free transfer
- on site-repairs possible; with replaceable application or complete cartridge design
- no external additional cooling necessary
- conveyor streams from up to 1,300 m³ / h and pressure to 100 bar
Type Series SL / SLH
 advancement of the screw spindle pumps - very robust and long-lasting
- reliable suction behaviour
- careful, pulsation-low support
- calibration-easy design
- easy to clean
- different achievment classes
SLH - food execution
- promoting and sterilising with a pump
- product-careful support
- the discontinuation of cleansing pumps and cleansing pipelines saves place and capital expenditure
- place savings by this \ " 2-in-1-Technologie \ " => servicing expenditure - optimum availability minimises
