1.Product Desciption:
BOAO SLGP twin screw pumps provide you with a range of convincing advantages that together result in the highest possible cost and production efficiency.
Using a modular system, we offers four pump sizes and different screw sets that cover a conveyance range of 40 l/h to 150 m3/h with a unit size up to 40 mm diameter. The different screw sizes make it possible to handle a wide range of flow capacities with the same viscosities, operating pressures and rotation speeds.

SLGP pumps feature no metal-to-metalcontact between the pump screws and the housing. This enables the conveyance of non-lubricating or corrosive and contaminated materials. 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.
Very flexible: The pump is designed to allow for reverse flow by simply
changing the shaft direction.
The pump come with a rotation speed of up to 3,600 rpm.

2.Working principle:
SLGP twin screw pumps are single-flow and self-priming. Two contact-free intermeshing screws and the pump housing form closed chambers that, according to the direction of rotation, constantly move towards the pressure discharge end of the pump. This axial system enables cautious, low-pulsation conveyance.
Different as impact force of centrifugal pump , squeezed of the lobe pump, reciprocating pulse of piston pump, our twin screw pump protects the media and maintains size, surface and visual integrity of the products.
This type twin screw pump is much better than other positive displacement pump, because of it big range of speed ,which up to 3600 rpm.

The 2-in-1 principle conveys and cleans in one pump. Due to the wide range of pump speeds ®C up to a maximum of 3,600 rpm, process cycles as well as CIP and SIP procedures are possible with just one pump.

The advantages are obvious: no need for a CIP pump or the associated piping, valves. It saves valuable space and reduces your investment costs. The conveyed material passes through the entire pump which enables excellent cleaning and hygienic results.

3.Technical parameters:
1.       Designed for reverse flow capabilities
2.       Shaft seal feeding makes the seal at the Atmospheric pressure, keep the pump°Įs seal ability at the high pressure.
3.       High self-susction ability, Self-priming down to a vacuum of less than -0.8 bar when the pump is filled.
4.       Big rang of medium transferred: viscosity from 1~500,000cst ,the maximum size of 40mm.
5.       Large range of speeds, from below 100 up to 3,600 rpm, make it possible to convey with one pump and also use it as a conveying aggregate
