Labyrinth of Sump Pump Spare Parts

In a sump pump, the labyrinth is typically located in the shaft sealing section. Its primary function is to serve as a physical barrier, preventing internal liquids or slurry from leaking out of the pump while keeping external contaminants from entering the pump.

Labyrinth seals are widely used to enhance the operating efficiency of sump pumps, especially under conditions of high temperatures, strong corrosion, or high slurry concentrations. Their labyrinth-style design effectively reduces friction and wear, significantly extending the pump’s service life.

Product features:
No contact required, low friction wear
Simple structure, easy to install and replace
Wear and corrosion resistant, suitable for various working conditions
Improves the reliability and service life of bearing components

Applicable equipment:
Submersible slurry pumps (such as models 65QV-SP, 100RV-SP, 150SV-SP, etc.)

Labyrinth Installation Instructions

Highly efficient and Wear-resistant: industrial solutions for 12/10ST-AH slurry pumps 3 Installation Location: The base should be installed on a flat, solid surface to ensure the entire pump remains level during operation. If the base is unstable, it can affect the pump's performance and service life.

Highly efficient and Wear-resistant: industrial solutions for 12/10ST-AH slurry pumps 3 Fastening: During installation, the base must be bolted securely to the ground or support frame. Bolts should be tightened to the specified torque to prevent loosening.

Highly efficient and Wear-resistant: industrial solutions for 12/10ST-AH slurry pumps 3 Alignment: The pump shaft and motor shaft must be precisely aligned to ensure smooth operation and avoid unnecessary wear or abnormal vibration.

Highly efficient and Wear-resistant: industrial solutions for 12/10ST-AH slurry pumps 3 Vibration Isolation: In high-vibration environments, rubber pads or other vibration isolation devices can be used to minimize the impact of vibrations on other pump components.

Highly efficient and Wear-resistant: industrial solutions for 12/10ST-AH slurry pumps 3 Inspection and Maintenance: After installation, the base and connected components should be regularly inspected to ensure they are not loose or damaged, preventing any adverse effects on pump operation.
