约翰•和诺尔•鲍诺曼泵业有限公司是世界上*的双
螺杆泵生产商，在单
螺杆泵领域也非常有名。鲍诺曼泵能提供令人信服的优点：由于泵的部件运行时无接触，与介质接触的部件就可以使用
不锈钢制造。泵可以输送腐蚀性、稀薄的以及高粘度的液体，同时对中性、碱性或酸性及介质也都可以安全输送。对于需要小心输送的非常稀薄的液体，使用鲍诺曼泵会很方便。

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
While pumping there is no metal-to-metal contact within the pump housing. This allows good pumping performance even with non-lubricating and corrosive and contaminated fluids.
As the pump rotates, the intermeshing of the two screws along with the pump housing form chambers. These chambers fill with the pumped fluid and move it from the suction side of the pump to the higher pressure discharge side of the pump.
The pump is designed to allow for reverse flow by simply changing the shaft direction. The suction becomes the dis-charge and vice versa, all without any modifications to the pump.
Wide range of applications
