Durable Sludge Transfer Screw Pump

Durable Sludge Transfer Screw Pump

Screw Pump Introduction

• Screw pump is a new type of pump which works according to the principle of rotary meshing volumetric pump.
• The main working parts are eccentric screw (rotor) and fixed bushing (stator).
• Due to the special geometry of the two parts, separate sealed cavities are formed respectively. The medium flows evenly from the axial direction. The internal flow rate is low, the volume remains unchanged, and the pressure is stable. Therefore, no eddy current and agitation will occur.
• The output pressure of each stage of the pump is 0.6MPa, the lift is 60m (clean water), and the self-priming height is generally 6m. It is suitable for conveying medium temperature below 80 ℃ (special requirements can reach 150 ℃).
• Because the stator is made of a variety of elastic materials, the pump is not competent for the transportation of high viscosity fluid and medium containing hard suspended particles or fiber.
• Its flow is proportional to the speed.
• Coupling can be used for direct transmission, or speed regulating motor, V-belt, gearbox and other devices can be used for speed change. The pump has few parts, compact structure, small volume and simple maintenance. The rotor and stator are vulnerable parts of the pump, with simple structure and easy assembly and disassembly.

Screw-type Pump Advantages

1.High Efficiency: Double screw Pumps are highly efficient, with low energy consumption and minimal losses due to friction. This makes them an ideal choice for applications where energy efficiency is a concern.

2.Consistent Flow: Double screw pumps provide a consistent flow rate, even when handling fluids with varying viscosity. This is because the screw geometry creates a continuous flow path, which eliminates pulsation and ensures a steady stream of fluid.

3.High Pressure Capability: Double Screw Pump is capable of generating high discharge pressures, making them ideal for applications where high head is required.

4.Minimal Maintenance: Double screw pumps have a simple, robust design that requires minimal maintenance. They have fewer moving parts than other pump types, reducing the risk of failure and extending the pump's service life.

5.Versatility: Double screw pumps can handle a wide range of fluid viscosities, from thin liquids to highly viscous materials. They can also handle abrasive and corrosive fluids, making them a versatile choice for a range of industrial applications.

6.Low Noise and Vibration: Double screw pumps operate quietly and with minimal vibration, reducing the risk of damage to surrounding equipment and creating a more comfortable working environment.

Single Screw Pump Structure Details

• This product is mainly composed of drive device, head assembly, housing, shaftless spiral, slot liner, feed port, discharge port, cover, base, etc.
• Driving device: The driving device is composed of motor and reducer.
• Housing: The housing is u-shaped or o-shaped, with a rain-proof cover on the top. The material is 304 stainless steel.
• Shaftless spiral: The material is carbon steel. The diameter of sprial can be customized according to customer needs.
• Slot lining board: It is made of hard-wearing nylon.
• Inlet and outlet: there are two types of inlet and outlet: square and round. The general inlet and outlet form is determined by the user.

Progressing Cavity Pump Application

1. Environmental protection: transportation of industrial sewage, domestic sewage and muddy water containing solid particles and short fibers. It is especially suitable for oil-water separator, plate and frame filter and other equipment.
2. Shipbuilding Industry: ship bottom cleaning, transmission of oil-water, oil residue, oily water and other media.
3. Petroleum Industry: transporting crude oil. In recent years, it has been especially successful in pumping the mixture of crude oil and water, which is thousands of materials deep underground, and the mixture of coal and water in the coal field, thus greatly reducing the cost of mechanical oil extraction and coal field gas. When the oil field reaches the late stage, the screw pump is used to inject polymer into the formation to increase the oil recovery.
4. Medicine, daily chemical: transportation of various viscous pastes, emulsions, ointments, cosmetics, etc.
5. Food canning industry: transportation of various viscous starch, edible oil, honey, sugar sauce, fruit pulp, cream, surimi, minced meat and their leftovers.
6. Brewing industry: all kinds of fermented mucking liquid, distiller's grains, grain product residues, all kinds of sauces, pulps and mucus containing massive solid substances.
7. construction industry: spraying and conveying of Cement mortar, lime slurry, coating and other pastes.
8. Mining industry: underground and sewage slurry containing solid particles in the mine are discharged to the ground.
9. Chemical industry: various suspensions, greases, colloidal slurries and adhesives.
10. Printing and paper industry: transportation of high viscosity inks, PVC polymer plastic pastes for wallpapers, pulp and short fiber pastes of various concentrations.
