In certain applications, customers deliberately choose to install their Tsurumi pump dry next to a sewage or wastewater tank. This setup offers clear advantages: maintenance work becomes faster, safer and more convenient. However, one crucial factor must be considered in dry installations – reliable motor cooling.
Submersible pump motors are normally cooled by the surrounding liquid. When a pump is installed permanently outside the tank, this natural cooling effect no longer applies. Without an appropriate cooling concept, overheating and premature wear would be unavoidable.
This is where Tsurumi's intelligent pump design comes into play.
Built-in cooling – even when installed dry
Tsurumi pumps designed for dry installation feature a proven cooling system:
- A cooling jacket guides the pumped liquid around the motor to dissipate heat effectively
- A bypass system ensures a constant flow into the cooling jacket
- The motor remains reliably protected against overheating, even when the pump is not submerged
Why this matters for your operation
- Reduced maintenance effort: Dry installations improve accessibility and shorten service times
- Longer service life: Stable cooling protects the motor from thermal stress
- Higher operational reliability: Correct cooling prevents unplanned downtime and costly repairs
