Standard 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.

(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

(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

Standard 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 materials

(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.

(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.

(1). Can screw pump dry running ?

No, the conveying elements are permanently in contact with one another, which means that dry running must be avoided in progressive cavity pumps. The Standard dry-running protection device offers reliable protection.

(2). What temperatures is suitable for using Standard pump ?

Standard progressive cavity pumps can be used at temperatures from -10 °C to 90° C
