Pumps and Seals
Self-actuating thermostatic valves protect pumps from excessive heat during low-flow operation and regulate mechanical seal water based on actual cooling demand.

Pumps and mechanical seals face different temperature-control challenges that can affect equipment reliability, water consumption, and operating costs. ThermOmegaTech® provides self-actuating thermostatic solutions for pump thermal relief and mechanical seal water support where controlled cooling water is required.
Pump Thermal Relief for Low-Flow Conditions
Booster pumps increase water pressure and flow where the incoming supply cannot meet building or equipment requirements, including multistory commercial buildings and other high-demand systems.
Because these pumps are sized to meet maximum demand, they may operate for extended periods at reduced or no flow. Under these conditions, excess pump energy can be converted to heat inside the pump. If that heat cannot escape, fluid temperature can continue to rise and damage seals, bearings, and other pump components.
Excessively heated water can also create a downstream scald risk in domestic water systems.
ThermOmegaTech® pump thermal relief valves respond directly to fluid temperature, automatically discharging heated water as needed to maintain an acceptable operating range. Self-actuating operation requires no external power or controls and limits discharge to when thermal relief is required.
Two valve configurations support different pump operating requirements:
- ECONO/HAT-RA – Designed primarily for domestic water booster pumps and other low- to medium-pressure water systems.
- HAT/RA-HP – Designed for higher-pressure applications, including fire pumps and other high-pressure water systems.
Mechanical Seal Water Support
Mechanical seals used in pumps, mixers, and other rotating equipment help contain process fluids and may require water for cooling, lubrication, cleaning, or flushing. Maintaining a controlled seal environment is especially important when handling hazardous, valuable, or contamination-sensitive fluids.
Continuous or manually controlled seal water can use more water than necessary because flow does not adjust as the cooling requirement changes. This increases water consumption, discharge volume, and wastewater treatment costs.
Insufficient or inconsistent seal water can also allow excessive heat to develop around the seal, contributing to premature wear and increasing the risk of leakage.
The EcoFlow® Mechanical Seal Support System provides seal water temperature control, automatically regulating cooling water according to the seal’s thermal load. This helps maintain a controlled seal environment without manual flow adjustment or external power.
EcoFlow® Reduces Water Use and Operating Costs
A major U.S. sugar producer installed EcoFlow® valves to reduce seal water consumption and the amount of water sent to drain.
Reducing this discharge also lowered wastewater and evaporation requirements, while the plant reported decreased maintenance costs and eliminated dry-running seal damage after implementation.
