Classic Circulator Pump High Efficiency Circulator Pump Boiler Circulator Pump Booster Circulator Pump

HES Domestic Circulator Pump

  • Pump-HES25-6

Plastmax HES series pumps are high-efficiency circulators, designed for heating systems. The pump features AUTO function which automatically adjusts the pump to system demands for optimal comfort and the lowest energy consumption as well as simple commissioning.

iPWM is available for HES25/8, 25/10, 25/12 and HES32/8, 32/10, 32/12.

Suitable for:

  • Commercial heating
  • Commercial hot water recirculation
  • Domestic hot water recirculation
  • Domestic heating
  • Industrial heating

Key Features

Constant speed mode

Three constant speed modes for constant flow applications

Constant pressure mode

• The pump maintains constant pressure regardless of the flow
• The preferred operation mode for under floor heating and 2 string systems with low flow variation
• Constant pressure curves (low and high)

Proportional pressure mode

• If the proportional pressure mode is selected, the differential pressure varies proportionally with the flow, i.e. higher flow means higher differential pressure
• Proportional pressure is the preferred choice for one-string systems with high flow variation
• Proportional pressure curve (high and low)

Autoadapt mode

• The factory setting, AUTO, analyzes the heating system and automatically adjusts the pump setting to meet the heating requirement. The result is optimum comfort and a minimum of energy consumption.
• AUTO can be used in 80% of the heating system

Night mode

The night mode reduces the power consumption to a minimum with power-saving features.
