China 2bl Series Twin Screw Pump for Oil Transfer

Working principle:
As the pump rotates, the intermeshing of the two screws along with the pump housing form cham-bers.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 discharge and vice versa.All without any modifications to the pump.
Operating limits:
Capacity 10 to 1,000m³/h head 4 to 35 m discharge flange size 5 to 14 in pressure up to4mpa temperature up to 150°c

Characteristics:
1.Smoothly transport various medium without vibra-tion and pulsation.The structure of pump casing ensures the pump chamber is full of medium as the sealing liquid.
2.High self - priming ability.
3.The special design of the twin screw pump en-sures high self - priming performance, i.E.A very small npshr value (up to 1.5 m).
4.The external bearing structure which is coupled with independent lubrication, allows transfer of vari-ous non-lubricating medium.
5.Synchronized gear drive and non contact rotating parts, ensure a dry running capability in a short peri-od.
6.Horizontal, vertical structure meet a wide variety of installation requirements.
7.Various heating methods including heating foot,full pump jacket heating or electrical heating, etc.,suitable for various working conditions.
8.Suitable for clean low-viscosity or high-viscosity medium without solid particles.
9.Corrosive medium can be handled and delivered with the use of special materials.
