Cooling Pump Tanks


Made from Polypropylene and available for above ground or below applications, Cooling tanks may be required in commercial laundering facilities incorporating a straining basket or purely designed to cool the flow of waste water to meet legal requirements.Available in sizes to suit small public laundromats or as large as 3000 litres to suit large industrial processing plants, our standard range dimensions as follows:

Cooling Pump Tanks: Your Ultimate Cooling Solution

When it comes to cooling systems, cooling pump tanks offer a host of benefits that can improve the efficiency of your operations. With a range of sizes from PT 250 to 22,712 litres, these tanks are available in both fibreglass and stainless steel, offering versatility for indoor and outdoor installations.

Key Features:

  • Premium-efficiency, close-coupled, non-overloading centrifugal pumps for optimised flow and pressure, leading to reduced electricity costs.
  • Programmable Logic Controller (PLC) for simplified operation.
  • Solid deck mounting for all pumps, ensuring rigidity, safety, and ease of service.
  • Grooved pipe connecting system, reducing the need for flexible couplings and eliminating pipe stress at start-up.
  • Full size pump suction legs on stainless steel tanks, designed to prevent pump damage and reduced performance due to vortexing and cavitation.
  • Factory-mounted thermometer for quick monitoring of process water temperature.

Why Use Cooling Pump Tanks?

Cooling pump tanks perform a variety of useful functions in cooling systems:

  • Additional System Volume: They provide extra system volume for smaller systems, preventing chiller short cycling.
  • Chiller Flow Stabilisation: They help in stabilising chiller flow in systems with dramatic variations in flow to cooling loads.
  • Chiller Load Smoothing: They smooth out chiller load for irregular or highly transient cooling loads.
  • Flow Equalisation: They assist in flow equalisation in split cooling recirculation systems with separate loops.
  • Physical and Non-Hydronic Functions: They accommodate drain-down volume, system water loss makeup, and stabilise cooling water supply for highly sensitive applications.


While cooling pump tanks offer many advantages, they aren’t technically required for all systems. They add to purchase, installation, and maintenance costs, and they require dedicated space. They can also impose hydraulic penalties on the systems where they’re installed. Furthermore, tanks introduce air and possibly dirt and debris into the water systems, which can increase corrosion.

Available Options

  • Single or dual standby pumps
  • Automatic standby pump switchover
  • Variable Frequency Drives (VFDs) for pumps and/or cooling tower fans
  • Tank cover
  • Electronic water make-up valve
  • Tank divider
  • Wave baffle
  • Mounted and piped heat exchanger
  • Mounted and piped strainer or bag filter
  • Rotary non-fused disconnect
  • Programmable logic controller (PLC)
  • Second pump deck
  • Tank support legs
  • OSHA-approved ladder, rail, and toe board.
In conclusion, cooling pump tanks provide a comprehensive solution for cooling systems. They offer a balance of efficiency, flexibility, and reliability, making them ideal for a broad range of applications. Your decision to use a cooling pump tank should depend on the specific requirements of your cooling system and the potential benefits to your operations.
