HSD series three screw pump is the companys response to marketdemand, the development of a specially designed high efficiency,low noise, use wide, long life products, it is particularlysuitable for viscosity 380cst ~ 460cst more than non-solidparticles, non-corrosive media delivery. Products designed andmanufactured in accordance with GB/T10886-2002。
Product Introduce
1、HSD series three screw pump by special shape of screw-typesurface composition, is an advanced displacement pump. Work, takethe initiative to screw driven by a prime mover in the rotation,the movement of liquid from the sealed chamber along the axis ofimports has been inhaled and continuous pulse-free delivery to theexit. Throughout the transfer process, due to the volume of sealedchamber did not change, of the transmission medium is notcompressed, so the pump runs smoothly, low noise, little vibration,flow rate are stable；
2、Lord, slave screw with axial low-pressure balance. Lord, inoperation in the slave screw is in tension, thus screw easydeformation driven by fluid pressure-driven rotary screw, master,slave screw between the non-contact, so no wear and tear screw；
3、Pump for the two-tier structure, mezzanine heating medium canpass to the heat pump heating medium；
4、Pump Import and Export orientation can be transformed accordingto user requirements, there is less advanced on the out (basemodel), make progress on the out, the left into the last out, rightinto the last out, etc. (see code instructions), user-friendlyon-site piping。
5、Simple product structure, machinery, high efficiency, easymaintenance, self-priming capability, long service life；

NO.3A 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
The structure type of the pump
The working flux of the pump-Q
The inlet pressure (or the vacuum degree)of the pump-P1
The outlet pressure of the pump-P2
The working temperature of the medium-T
The medium viscosity at the working temperature-v
The feature of the medium
