Product Overview

The I-1B Stainless Steel Single Screw Thick Slurry Chemical Pump is a single screw positive displacement rotary pump. It operates by rotating an eccentric single screw rotor inside the stator, continuously transferring slurry from the intake to the discharge outlet. This pump is designed to handle high viscosity, high concentration media, and suspensions containing solid particles.

Key Features

  • High Viscosity and High Concentration Media Handling: Capable of handling high viscosity slurries and suspensions with solid particles.

  • Continuous and Smooth Flow: Provides stable, continuous flow without pulsation, agitation, or leakage.

  • Stable Discharge Pressure: The discharge pressure is independent of the speed and can maintain high discharge pressure even at low flow rates.

  • Powerful Self-Priming Ability: Offers excellent self-priming capability, making it suitable for systems requiring forward and reverse pipeline flushing.

  • Low Vibration and Low Noise: Features low vibration and low noise during operation, ensuring smooth and quiet operation.

Engineering Overview

The I-1B series uses an eccentric rotor and elastomeric locator to form sealing chambers, allowing steady movement of the media along the helical cavity. The pumping process is smooth and continuous, maintaining stable pressure. The discharge pressure is independent of the speed, ensuring high discharge pressure even at low flow rates.

Typical Applications

The I-1B series single screw pump is widely used in:

  • High Viscosity and High Concentration Slurry Transfer: Especially suitable for pumping high viscosity slurries (up to 10000 Pa·S) and suspensions containing solid particles.

  • Precise Flow Control: Ideal for applications requiring precise flow control, such as chemical processing, food production, and pharmaceutical industries.

  • Pipeline Flushing and Water Replacement: Provides forward and reverse flow capabilities, ideal for pipeline flushing and water replacement systems.

System Configuration

Pump Components

The I-1B single screw pump primarily consists of the pump casing, eccentric screw rotor, elastomeric locator, transmission components, and the drive unit. The pump casing can be made of cast iron or stainless steel, and the gearbox and wet parts may be made partially or completely of stainless steel to meet different corrosion resistance and hygiene requirements. The elastomeric materials include wear-resistant rubber, food-grade rubber, and oil-resistant rubber.

Components and Supply

The key components of the I-1B series pump include the eccentric screw rotor, elastomeric locator, drive unit, and transmission components. These parts are made from durable materials to ensure long-term stability and reliability, with customization options available for specific operational conditions.

Technical Service

The I-1B series single screw pump offers comprehensive technical support services, including installation, commissioning, regular maintenance, and troubleshooting to ensure the long-term stability and reliability of the equipment.

Operating Conditions

  • Applicable Media: Suitable for transporting high viscosity slurries, suspensions, and media containing solid particles.

  • Maximum Media Viscosity: ≤10000 Pa·S.

  • Conveying Mode: Continuous positive displacement, providing stable flow.

  • Flow Rate Adjustment: Adjustable flow rate through speed control.

  • Bidirectional Operation: Supports forward and reverse pipeline flushing or water replacement.

Service Conditions

Regular inspection of the pump’s sealing system, eccentric screw, and stator components is recommended to ensure efficient and safe operation and to extend the pump’s service life.

Protection Features

The I-1B series pump is equipped with multiple protection features, including overcurrent protection, temperature monitoring, and liquid level protection systems, ensuring that the pump can stop operating in abnormal conditions to prevent equipment damage.

Selection Standards

When selecting the pump model, consider factors such as the temperature of the media, viscosity, solid particle size, and the required flow and head of the pump to ensure the selection of the most suitable configuration.

Operating Manual

I. Installation Instructions

Follow the general layout drawing and the installation dimensions provided in the manual to pour the foundation and determine the anchor bolt positions. The suction port direction should generally not be altered arbitrarily.
Use a spirit level to check the foundation surface for levelness. After the foundation concrete has cured, install the pump on the foundation.
Align the motor shaft and pump shaft to ensure coaxiality. The deviation between the two shaft centerlines should not exceed ±0.2 mm. If the shafts are misaligned, it can cause vibration and bearing overheating, potentially damaging the pump.
The suction and discharge pipelines should be independently supported; the pump body must not bear the weight of the pipelines.
When the pump is used for tank emptying, a bottom valve may be omitted, but a shut-off valve and strainer should be installed on the suction line to prevent debris from entering the pump.
If the pump is installed above the liquid level, a bottom valve must be installed at the suction line’s end. The throat area of the bottom valve should be 50% larger than the cross-sectional area of the suction pipe.
Before installation, thoroughly clean the pipelines to remove welding slag, metal chips, and other debris to avoid their entry into the pump upon startup.

II. Startup Procedure

  1. Prepare the necessary wrenches and tools.

  2. Check that the foundation, bearings, and oil chamber are adequately lubricated.

  3. Ensure the hollow shaft and shaft seal are correctly adjusted. The packing gland should not be overtightened; slight leakage is permissible.

  4. Rotate the coupling by hand or with a pipe wrench to ensure there are no obstructions, rubbing noise, or jamming. If any issues are found, remove them before starting the pump.

  5. Fill the pump casing 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 idle for a long period, drain the liquid from the pump casing and flush it with clean water or steam.

III. Operation

  1. Regularly monitor the temperature rise of the pump and motor bearings. The temperature should not exceed 75°C.

  2. Replenish the lubricant in time to ensure proper bearing lubrication.

  3. If abnormal noise or excessive vibration occurs during operation, stop the pump immediately, inspect the cause, and resolve the issue before restarting.

  4. If the flow decreases significantly, the rubber stator may have worn out and should be replaced before restarting the pump.
