Product Introduction

The Vertical Screw Pump with Pedestal is a robust, space-saving, and highly efficient positive displacement pump designed for continuous transfer of viscous, abrasive, and multiphase fluids. Its vertical installation with an integrated pedestal base provides excellent stability, compact footprint, and ease of maintenance, making it an ideal solution for industrial, wastewater, chemical, and food applications where space and reliability are critical.

Unlike traditional horizontal pumps, the vertical screw pump is configured with the motor mounted above the drive shaft, while the pump body is immersed in the medium. This arrangement allows for self-draining operation, reduced floor space, and easy integration into tanks, pits, or reactors. The pedestal design adds structural strength and supports the vertical alignment, ensuring smooth operation with minimal vibration.

The pump operates on the principle of progressive cavity motion, utilizing a helical rotor and stator assembly that forms continuous sealed cavities. As the rotor turns, these cavities move axially, gently conveying the fluid without pulsation or turbulence. This makes the Vertical Screw Pump with Pedestal suitable for shear-sensitive, viscous, or solid-laden fluids that cannot be handled effectively by centrifugal pumps.

With materials available in 304, 316L stainless steel, carbon steel, or abrasion-resistant alloys, the pump can be adapted for a wide range of industries. The design ensures low noise, high efficiency, and long service life, meeting the demanding requirements of modern processing facilities.

Technical Parameters

The Vertical Screw Pump with Pedestal is built for reliability, modular design, and flexible operation. The pedestal ensures the pump’s vertical alignment, reduces mechanical stress on the drive shaft, and simplifies installation in tight or deep areas such as tanks, wells, or filter press sumps.

Operating Instructions

Proper installation and operation of the Vertical Screw Pump with Pedestal ensure optimal efficiency and long lifespan.

Installation Guidelines

1. Positioning: Install the pump vertically over the tank or pit so that the suction inlet is submerged in the fluid.

2. Foundation: Secure the pedestal on a rigid base to prevent vibration and misalignment.

3. Alignment: Ensure the coupling between the motor and pump shaft is precisely aligned.

4. Piping: Use flexible couplings or compensators to absorb vibration and prevent stress.

5. Priming: Fill the suction chamber before startup to prevent dry running.

Operating Procedure

1. Start-Up:

• Verify direction of rotation.

• Start at low speed, especially with viscous or solid-laden fluids.

• Gradually increase speed to operating level.

2. Monitoring:

• Observe flow rate, pressure, and temperature.

• Check for unusual vibration, noise, or seal leakage.

3. Feeding Filter Presses or Reactors:

• Adjust flow rate using a variable frequency drive (VFD).

• Maintain stable feeding to ensure consistent pressure and product quality.

4. Shutdown:

• Stop the pump and flush with cleaning solution or water (especially for sticky materials).

• Drain residual fluid from the system.

Maintenance Tips

• Lubrication: Regularly lubricate bearings and mechanical seals.

• Inspection: Check rotor, stator, and seals for wear after each operating cycle.

• Seal Replacement: Replace seals immediately if leakage occurs.

• Cleaning: Use CIP systems for sanitary models; flush abrasive or corrosive media after each use.

• Storage: When idle for long periods, clean thoroughly and coat metallic parts with anti-rust oil.
