80W Submersible Water Pump for CNC Water Cooled Spindle Motor

The Zhong Hua Jiang 80W submersible water pump is specially designed for CNC water cooled spindle motor cooling systems. Suitable for 0.8kW, 1.5kW and 2.2kW water cooled spindle motors, it delivers stable water circulation to maintain spindle temperature during long-term CNC routing, engraving, cutting and milling operations.

Key Features

High Efficiency CNC Cooling Pump

This 80W submersible water pump provides reliable cooling circulation for CNC spindle motors. With a maximum flow rate of 3500L/h and a maximum lift height of 3.5m, it helps prevent overheating and extends spindle service life.

Dry Burn Protection

The built-in thermal protection chip automatically disconnects power when water levels become insufficient and motor temperature reaches approximately 80°C. Once cooled, the pump automatically resumes operation, reducing maintenance risks.

Durable ABS Housing

Constructed from impact-resistant ABS material, this water pump offers excellent durability, corrosion resistance and long operating life. Four strong suction cups keep the pump securely fixed inside the water tank.

Adjustable Water Flow

An integrated flow control knob allows users to easily adjust water output according to spindle cooling requirements and tank size.

IPX8 Waterproof Design

The fully sealed internal circuit protects against water penetration and ensures reliable operation in continuous cooling applications.

Wide Range of Applications

Suitable for CNC water cooled spindle motors, aquariums, fountains, hydroponic systems, fish tanks and other water circulation applications.
