Our Water Tank designs range from 150 to 5,000 gallons+ and are offered in carbon steel, stainless steel or MDPE Medium Density PolyEthylene. The WT series tanks aer custom designed with or without a baffle and sized to accomodate a variety of pump configurations. SEveral option scan be added to the tank for ease of operation.
DURABLE & DEPENDABLE
All WT Series Pump/Tank Station components are mounted to a heavy-gauge solid deck.
1. Available in 1/4” Carbon or 3/16” Stainless Steel plates or MDPE Medium Density PolyEthylene.
2. Internal coal tar epoxy coating. Polyurea Polycoat is available as an option for the carbon steel tanks.
3. NEMA-rated control panel to synchronize pump and tank services.
4. Pump motor with electrical contactor and overload that includes start & stop buttons, fuses and pilot lights.
5. Closed-coupled process pump including full-flow valves and headers reduce pressure drop and sized to assure laminar flow.
6. To ensure total water turnover, pump suction ends are extended into the tank and are cut at a 45° angle to prevent vortexing and cavitation.
7. A butterfly valve at the pump suction permits pump removal for replacement or service without the need to drain or stop the entire system.
8. A flow-balancing valve at the pump discharge completes the trim to provide pump operation at the design rate of flow.
9. Process pumps also include check valve in the discharge line to prevent drain back and allow higher operating volume as well as a liquid-filled pressure gauge to indicate pump discharge pressure.
10. Cooling Technology’s unique bottom drain with ball valve minimizes solids and allows full drainage.
Considerations when selecting a pump tank for a cooling tower or chiller system:
1. OPERATING. Have enough water in the tank.
2. TO PREVENT PUMP CAVITATION (air pulled into the pump along with water). Be sure that about 18” of water is above the pump suction.
3. TO ALLOW FOR WATER / AIR SEPARATION (air is induced into the water in the cooling tower to promote evaporation, not as critical with a chiller system).
4. TO HAVE THERMAL STORAGE to smooth out demand spikes.
5. START-UP. Have enough water in the tank.
6. TO FILL THE SYSTEM… and have enough operating volume remaining.
7. SHUT DOWN… Have enough water in the tank.
8. TO CONTAIN DRAIN BACK… from the tower or chiller without overflowing.
9. TO HANDLE DRAIN BACK… from the process piping (generally the water in the process piping is trapped so that most of the process water remains in the piping).
