S T D ® ST Hopper Screw Pump with Hopper in Block Construction and Flanged Drive
Universally applicable – the S T D® SThopper-Shaped Progressing Cavity Pump
S T D® ST Series hopper type single screw pump, compact structure, ideal for conveying brittle media
The St-series hopper type single screw pump has square/rectangular hopper, and has a connecting rod between propeller and squeeze cavity, which can be used in most industries to provide continuous, stable, steady and low pulsating conveying. This special design ensures that the material is better fed into the cavity between the rotor and the stator.
The other advantage of the single screw pump is that it can measure any medium in direct proportion to the rotational speed. ST series hopper type single screw pump for flange joint reducer motor straight-linked structure, compact and affordable.
Characteristicsof the STD® ST hopper-Shaped Progressing Cavity Pump
1 Hopper cavity with rectangular inlet flange and spiral feeder and squeeze cavity,
To facilitate the flow of slow and paste medium into the rotor and stator between the cavity.
2 Continuous low pulsation transmission, not affected by pressure and viscosity fluctuation
3 The conveying capacity is proportional to the rotational speed, and can achieve high precision measurement in the whole speed range;
4 High pressure no valve transmission
5 The stator with hopper type feed mouth can make the medium easy to enter the conveying cavity
6 Low noise, small vibration
7 Wide range of flow and pressure
Advantages of STD® ST hopper-Shaped Progressing Cavity Pump offers you:
The advantages of the St-series hopper type single screw pump:
1 Variable Modular System
2 Different rotor/stator geometry and wide range of materials used
3 Durable compact direct-linked structure
4 Connector suitable for various applications
5. Standard mechanical seals,other seals available
The STD® ST Progressing Cavity Pump is available
1 Maximum flow can reach 200 m3/h
2 Maximum pressure up to 48 bar
3 Using different materials, from steel to nickel-chrome to high acid-resistant materials such as double steel, HAalloy and titanium alloy
4 Different stator rubbers, from the high abrasion resistance of natural rubber to oil, acid and alkali-resistant rubber to fluorine rubber and all fluorine
5 Different mechanical seals,packing gland and special mechanical seals.
6 Smooth conveying medium
7 The pump connection conforms to the domestic and the international standard and the specialized design module
8) Easy Maintenance
STD hopper type single-screw pump can be used in all industries ,
with continuous, stable, steady and low pulsating transmission of various
media, and rotational speed proportional to the measurement of almost all
media. Use hopper and screw feeder to facilitate conveying of slow-moving
The STD® ST series hopper type single-screw pump is mainly used for these characteristics of the media:
1 Slow flow and low fluidity of 2) medium containing 3) of solid materials) shear sensitivity of 4) lubricity or non-lubricity 5)Thixotropy and distensibility 6)abradability 7) viscidity
1) High viscosity, compaction, fragile,media that do not produce a bridging
2)Slow flow and non-free flow, solid material fluid medium
Thickening or concentrated sludge, sticky paste, cod liver oil, fish eggs, sausage sauce, lard, dough, potato residue, etc.
Excellent construction system of straight-linked single screw pump
(1) Rotor: abrasion resistance, corrosion resistance design
(2) Stator: Tube vulcanization, both ends sealed, using a variety of rubber, plastic and metal materials.
(3) Connecting Rod:The connecting rod is provided with a screw feeder and a squeeze chamber, which facilitates the feeding of the material into the cavity between the rotor and the stator, with two universal joints that transmit power from the drive device to the rotor.
(4) Shaft sleeve: The standard structure is a single end face, can be positive and negative rotating, wear-resistant mechanical seals. According to user requirements, can also be used by different manufacturers to provide different types of single/double end mechanical seals, assembly and other special sealing, and packing seals
(5) Suction chamber and discharge body: the suction chamber is fitted with a square/rectangular hopper. Hopper size can be adjusted according to specific application.
Use flanges or threaded connections that conform to DIN standards and other international standards. The materials used are cast iron, carbon steel stainless steel and special materials according to customer's requirements.
(6) Bearing SEAT structure: The whole pump runs more smoothly.
(7) Universal joint: The screw pump has the correct joint, which has a decisive influence on the operation reliability and life cycle cost.
(8) Bracket: independent support foot; Rod; Simplifies assembly and maintenance procedures
(9) Sew Reducer Motor: The standard-equipped reducer motor for the screw pump is a German sew or Nord, which can also match customer requirements.
The maintenance of vulnerable parts
1 Rotor and stator
The wear rate of the two components is related to many factors, such as the wear characteristics, rotational speed and pressure of the pumping material. When the pump performance is reduced to meet the requirements, the stator and rotor should be replaced with a component or two simultaneous replacement.
2 Drive shaft
The wear rate of the filler contact surface depends on many factors, such as the abrasion and rotational speed of the medium. Constant maintenance of filler can maximize the service life of the pump shaft. When shaft seals fail, the shafts and fillers need to be replaced at the same time.
3 Connecting rod Assembly
Regular maintenance and lubrication can maximize the service life of the connecting parts. When the parts appear obvious wear and tear, should replace the connecting parts connecting the component, if necessary, can replace the whole shaft ,
