Технические характеристики
Real Loop Matching
Our pumps are selected with actual glycol ratio, fluid temperature, and system pressure in mind, helping each unit perform reliably beyond clean-water calculations.
Stable Efficiency
The hydraulic design helps the pump stay closer to its best efficiency range, reducing unnecessary energy loss and flow instability in daily operation.
Smoother Suction
We refine the inlet and impeller passage to support smoother fluid entry, helping reduce cavitation risk, noise, and pressure fluctuation.
Easier Maintenance
Our pump structure is built with service work in mind, allowing faster inspection and replacement of key wear components during scheduled HVAC maintenance.
Get Expert Chilled Water Pump Sizing
Glycol concentration, loop delta-T, and antifreeze ratio all affect pump selection in closed chilled water systems. Incorrect sizing leads to seal failure, suction cavitation, or chronic underperformance at part load. Share your glycol type, duty points, and system pressure profile. Our engineers will return a verified pump selection with glycol-compatible seal specifications and a hydraulic equivalent submittal within 48 hours.

Why Choose Mislier Chilled Water Pumps
We manufacture our commercial HVAC pumps with specialized metallurgy and seals to withstand the harsh conditions of low-temperature circulation.
Anti-Sweat Protective Casing
To prevent external rust caused by continuous pipe condensation, we apply thick anti-corrosive epoxy coatings to our pump casings. The outer geometry is designed to easily accommodate standard thermal insulation jackets.
Glycol-Grade Mechanical Seals
We use high-grade EPDM elastomers and Silicon Carbide faces as standard. This seal combination is specifically rated to handle the aggressive chemical properties of ethylene and propylene glycol without weeping.
Optimized Curves for Variable Flow
Our impellers are engineered with steep, stable hydraulic curves. This ensures the pump maintains positive pressure and prevents suction cavitation even during rapid motor speed adjustments in VPF systems.

Chilled Water Pump FAQs
How do these pumps help reduce electricity costs during low occupancy periods?
Our pumps pair high-efficiency motors with VFD compatibility. When building heat load drops at night or on weekends, pump speed reduces automatically to match demand—cutting chiller plant electricity costs significantly.
Will the condensation forming on the pump body cause it to rust
Cold water running through a warm mechanical room creates constant sweating on the pump casing. We solve this by applying a thick multi layer epoxy coating to every unit. This waterproof barrier stops moisture from reaching the cast iron surface. Our design also ensures the pump body can be easily wrapped with thermal insulation to stop condensation from forming in the first place.
Can these seals handle high concentrations of glycol or brine mixtures?
Yes. We specify silicon carbide seal faces with high-grade EPDM elastomers as standard—materials rated to stay flexible at low temperatures and resist chemical erosion from ethylene and propylene glycol mixtures.
Is it possible to replace an old pump without welding or moving pipes
Our pumps match standard international flange and bolt patterns, so contractors can remove an old unit and bolt ours directly into the existing pipeline,no welding, no pipe reconstruction, minimal labor cost.
What prevents air bubbles and noise in a closed chilled water loop
Our impellers use a hydraulic profile that drives air toward system separators, while precision dynamic balancing of every rotating assembly eliminates vibration transmission through the building structure.
