HSG series of three screw pump is the company based on marketdemand, in the HSN family developed on the basis of another rangeof products, it can compley replace the internal 3G series pump.GB/T10886-2002 designed and manufactured in accordance withnational standard.
HSG series of three screw conveyordisplacement axial rotor pump, which consists of a specialcomposition of spiral shaped curve surface, when the screwrotation, the movement of liquid from the sealed chamber along theaxis of imports has been inhaled and continuous, non-rippletransport to the exit, running smoothness, with low noise, no pulsemaster-stroke hydraulic balance, fluid pressure-driven rotation, soscrew no wear, long life with mechanical seal, no leakage simplestructure, compact in size Small, light weight, high efficiency,has a strong self-absorption capacity, energy-saving effect is goodinstallation, use and maintenance is convenient.
HSG series of three-screw pump can transport all kinds of non-solidparticles, non-corrosive oil lubrication oils and similar liquids.Medium viscosity of 3.0 ~ 760mm2 / s, flow rate range of 4.3 ~ 102m3 / h, the maximum pressure of 2.5Mpa, the maximum temperature of150 ℃. Widely used in machinery, petroleum, chemical industry,metallurgy, electric power, shipping and food sectors.
HSG series three screw pump type for horizontal installation.

Code Description
A few tips on pump selection：
1、Please select the appropriate rotational speed in accordancewith the viscosity of the liquid, so as to ensure that NPSHr of thepump can meet the practical suction conditions of our customers.
2、If the medium viscosity exceeds the range on the performancetable, please contact our technology department. We will alwaysprovide you with satisfactory service.
3、After the pump selection, please ask for the measurements of thepump and the electrical machinery unit’s accessories for the basicconstruction design.
4、Whether we will deploy the safety valve depends on customer’srequest and the safety valve only protect the pump for a instant,can not be the overflow valve of conduit.
Please provide the following data when you order pumps：
1、The structure type of the pump
2、The working flux of the pump-Q
3、The inlet pressure (or the vacuum degree)of the pump-P1
4、The outlet pressure of the pump-P2
5、The working temperature of the medium-T
6、The medium viscosity at the working temperature-v
7、The feature of the medium
8、Whether the electrical machinery is anti-explosive
9、The demands for accessorie
