I. N-type Feeding Screw Pump Overview
This hopper-type screw pump features a rectangular hopper and a propeller on the connecting rod. It is suitable for non-free-flowing media containing liquids. When conveying slag-liquids, a stirring rod can also be installed to prevent sedimentation. For high-concentration slag-liquids, a large hopper with crushing function can be added to prevent clogging. The pump can be equipped with various drive options, and is most suitable for a three-phase gear reducer motor.

Custom hoppers can be customized for special materials at the inlet, ensuring smooth feeding and discharge, resulting in pressure-free feeding and discharging, higher pump efficiency, and longer service life, completely eliminating customer problems. Inlet and outlet options include clamp quick-release, flange, internal thread, external thread, and union. Pump body materials include cast iron, 304 stainless steel, 316 stainless steel, and 316L stainless steel, depending on the specific media requirements.
II. Scope of Application
The N-series feed screw pump utilizes a special screw propeller structure for conveying viscous liquids. Its primary applications are as follows:
Environmental Protection: Transporting industrial and domestic wastewater, sludge containing solid particles and short fibers, and is particularly suitable for oil-water separators and plate-and-frame filter presses.
Food Industry: Transporting ketchup, mashed potatoes, peanut butter, yogurt, fresh cream, ice cream, cheese blocks, whey, beer, wort, yeast, fruit juice drinks, vegetable pastes, jams, jellies, etc.
Pharmaceutical Industry: Transporting various types of pill pastes, extracts, emulsifiers, cough syrups, biological products, cod liver oil, royal jelly, etc.
Household Chemical Industry: Transporting shampoo, hand soap, toothpaste, cosmetics, soap, etc.
Paper Industry: Transporting glue, high-viscosity inks, wallpaper, PVC polymer plastic pastes, and pulps of various concentrations and short-fiber slurries.
Petroleum Industry: Transporting crude oil, crude oil-water mixtures, and coalfield gas-water mixtures. Construction Industry: Spraying of cement mortar, lime slurry, paint, and pastes
Mining Industry: Solid particles in mines, groundwater, and sewage slurry
Chemical Industry: Various suspensions, oils, colloids, and adhesives
Shipbuilding Industry: Wheel bottom cleaning, oil-water, oil residue, and oil-wastewater conveying.
Industrial Boilers and Power Plants: Coal-water slurry conveying
Applicable Applications
1. Conveying high-viscosity media.
2. Conveying media containing solid particles or fibers.
3. Requires continuous, stable pressure without periodic pressure fluctuations.
4. Requires minimal agitation and does not disrupt the inherent structure of the conveyed media.
5. Low noise.
