1. Domestic hot water recirculation

2. Domestic heating and hot water circulation systems

3. Hot water heater circulation systems

4. Hot water circulation in water supply systems of private houses and flats. 

Easy installation and operation 

Pump runs once the power is connected and works with maximal rotation speed all the time. 

Low noise and high comfort

Noise index: ≤42dB(A)

Low energy consumption

Power consumption lowest to 5W

Multiple protection

With over-current protection

Quick release power plug

Start-up and stop the pump quickly. 

1. The pumps can be used for open and closed systems. Constructioned for indoor installation.

2. A water-conducting part of these pumps is made of corrosion-resistant brass to protect them from chemical contact with hot pumped water.

3. The pumps are energy-efficient and silent due to their advanced Functional drawing of multi-circuit hot water recirculation.

4. Reduced installation lengths and compact size of these pumps allow integrating them into the recirculation circuit even in the tightest space. If applicable, dismountable design will allow easily purging the flow part of the pump.

Pumped liquids

1. Pure, non-viscous, non-aggressive, and nonexplosive liquids without solids or fibers. • Cooling liquids without mineral oils.

2. Domestic hot water with hardness max. 14 °dH, max. 110 °С.

3. Softened water. Kinematic water viscosity υ = 1 mm2/s (1 cSt) at 20 °C. When a circulator pump is used to pump a more viscous liquid, performance of the hydraulic system decreases.

Liquid temperature

From +2 to +110 °С. It is recommended to maintain a temperature from 50 to 60 °С to minimize lime deposits and prevent Legionella.

Ambient and liquid temperatures

A temperature of pumped liquid should always be higher than ambient temperature. Otherwise, there can appear condensation in the housing.

Maximum system pressure

Pumps with units (PN 10): 1.0 MPa (10 bar).

Inlet pressure

To avoid cavitation noise and pump bearings damage, the following minimal pressure should be set up for an inlet port:

Liquid temperature

75 °C

90 °C

110 °C

Inlet pressure

0.5 m

5 m

10.8 m

0.049 bar

0.5 bar

1.08 bar

 

Construction

INSTANT pumps design allows disconnecting the motor of the pump from the housing for easier maintenance. A rotor bearing is lubricated with pumped liquid. The pumps feature:

1. parts contacting with pumped liquid are isolated from stator placed in a sealed stainless steel case;

2. friction decrease in a bearing and absence of slop provide significant decrease in consumed power and noise.

INSTANT pumps are equipped with single-phase permanent-magnet motors.

The motor has full electric resistance and heat protection.

The motor does not require any additional protection.

Enclosure class: IP 44.

Insulation thermal resistance class: H.
