Product Description
Product Introduction
The I-1B stainless steel single screw thick slurry chemical pump is a single-screw positive displacement rotary pump.
It uses an eccentric single-helix rotor rotating inside a double-helix stator. As the rotor turns, the thick slurry in the helical cavities is pushed from the suction inlet to the discharge outlet, achieving continuous conveying.
Structure and material configurations:
I-1B type: Cast-iron casing with standard steel transmission components, suitable for conveying general neutral slurry.
I-1B type (stainless rotating parts): Transmission components (main shaft, screw, and flexible shaft) are made of stainless steel, suitable for conveying mildly acidic or alkaline slurry.
I-1B type (all stainless wetted parts): Transmission components and all slurry-contacting casing parts are made of stainless steel, suitable for food, pharmaceutical and corrosive slurry applications.
Rubber stators are available in general wear-resistant rubber, food-grade rubber, and oil-resistant rubber for user selection.
Drive options include: direct motor-to-pump shaft drive, motor via gear reducer to pump, and motor via V-belt pulley to pump shaft.
Motors are available in totally enclosed, explosion-proof, and electromagnetic speed-regulating types.
Product Features
This pump is widely used in chemical, pharmaceutical, brewing, papermaking, food and many other fields.
1. Capable of conveying high-concentration, high-viscosity slurry (< 10,000 Pa·s) and suspensions containing solid particles.
2. Delivers a stable flow with no overflow, pulsation, agitation or shearing of the slurry.
3. Discharge pressure is independent of speed, so high discharge pressure can be maintained even at low flow rate.
4. Flow rate is proportional to speed; flow can be adjusted by a variable speed device or high-speed motor.
5. Strong self-priming capability. Flow direction is changed by reversing the pump rotation, making it suitable for systems requiring forward and reverse pipeline flushing.
6. Smooth operation with low vibration and low noise.
7. Simple structure, easy disassembly and convenient maintenance.
Application Range
All wetted parts of this series chemical pump are made of high-quality stainless steel. The screw stator is made of medium-hardness rubber, making the pump suitable for food processing, pharmaceutical, chemical and many other industries. Typical applications include:
1. Sugar mills: transfer of molasses, sugar juice, filter cake, beet pulp, etc.;
2. Canning plants and food factories: loading and conveying milk powder, starch, honey, coffee, milk, cream, edible oil, various vitamin solutions, maltose, tomato paste, jams, mayonnaise, ice cream and more;
3. Breweries and distilleries: dosing and transferring alcoholic beverages, flavors, fermentation liquids, feeding filter presses, and conveying spent grain and other residues;
4. Fish processing plants: transfer of cod liver oil, fish oil, fish floss, fish residues, etc.;
5. Fruit processing plants: transfer of sugar solutions and fruit juices, crushing of citrus and fruits, and feeding hoppers and mixers;
6. Grain and oil processing plants: filling and conveying edible oils, rice and corn starch, etc.;
7. Meat processing plants and slaughterhouses: conveying fats, tallow extraction, packaging filling and waste liquid transfer;
8. Pharmaceutical plants: feeding and transferring various vitamin solutions, medicinal liquids, emulsions, suspensions, brine, saline sludge, medicinal residues, etc.;
9. Chemical industry: transfer of acids and alkalis, various suspensions, oils, latex, chemical dyes, paints, adhesives, ointments and pastes; especially suitable for conveying various high-viscosity materials and media with solid particles that cannot be handled by ordinary centrifugal pumps;
10. Ink preparation and transfer in printing industry;
11. Papermaking: conveying pulp and ink solutions;
12. Petrochemical plants: transfer of oil products, fats, waste liquids and sludge;
13. Acetylene plants: transfer of carbide sludge;
14. Construction industry: conveying mortar, lime slurry, sand slurry, cement slurry, etc.;
15. Water pumping, material conveying and dosing in feed processing lines;
16. Widely used for industrial and domestic sewage and sludge treatment. Sewage typically contains many suspended solids, is corrosive and viscous, and often contains solid particles, making chemical screw pumps particularly suitable for transfer;
17. Nuclear facilities: conveying contaminated water, contaminated liquids and other radioactive or hazardous media;
18. Mines: transfer of mine drainage and sludge.
In addition, it can be used in steel, shipbuilding, ceramics, leather and water treatment industries, among many others.

Installation and Operation
I. Installation Instructions
According to the general arrangement drawing and the installation dimensions provided in the manual, pour the foundation and determine the positions of the anchor bolts. In general, the suction inlet direction should not be changed arbitrarily.
The foundation surface should be leveled with a spirit level. After the foundation concrete has cured, mount the pump onto the foundation.
Align the motor shaft and pump shaft so that their coaxiality is ensured. The offset between the two shaft centerlines must not exceed ±0.2 mm. If the shaft centerlines do not coincide, vibration and bearing overheating will occur and may even damage the pump.
The suction and discharge pipelines should be independently supported by their own supports; the pump casing must not bear the weight of the piping.
When the pump is used for tank-emptying service, a bottom valve may be omitted, but a shut-off valve and strainer should be installed in the suction line to prevent foreign matter from entering the pump.
If the pump is installed above the liquid level, a bottom valve must be installed at the end of the suction line. The throat area of the bottom valve should be more than 50% greater than the cross-sectional area of the suction pipe.
Before installation, the pipelines must be thoroughly cleaned to remove debris such as welding slag and metal chips to prevent them from being sucked into the pump at startup and causing accidents.
II. Start-up Procedure
1. Prepare the necessary wrenches and tools.
2. Check that the base, bearings and oil chamber have adequate lubrication oil.
3. Check whether the hollow shaft and the shaft seal are properly adjusted. The packing gland must not be overtightened; a slight dripping leakage is permissible.
4. Turn the coupling by hand or with a pipe wrench to ensure there is no foreign matter, rubbing noise or jamming inside the pump. If any is found, remove it before starting the pump.
5. Fill the pump chamber completely with liquid. Do not run the pump dry to avoid damaging the rubber stator.
6. Fully open the discharge gate valve.
7. Start the motor.
Shutdown
1. Close the suction valve.
2. Close the discharge valve.
3. Stop the motor. If the pump will be out of service for a long period, drain the liquid from the pump chamber and flush it with clean water or steam.
III. Operation
1. Regularly check the temperature rise of the pump and motor bearings; the temperature must not exceed 75°C.
2. Replenish lubricant in time to ensure good bearing lubrication.
3. If abnormal noise or excessive vibration occurs during operation, stop the pump immediately and inspect to eliminate the fault.
4. If the flow rate decreases significantly, it indicates that the rubber stator has been worn and should be replaced before restarting the pump.
