CIRCULATION PUMP AND PRESSURE DROP 

DualTherm

 boiler can be installed with a circulation pump supplied by DOMUSA TEKNIK. This pump 

can be a conventional pump or a high efficiency circulation pump. 

32.1

 

High efficiency circulation pump 

The 

high efficiency circulation pump

 allows savings of up to 70 % in energetic consumption in 

comparison to conventional pumps. The pump can be adjusted in two ways: 

1-Constant speed I, II, III (traditional mode): 

The pump operates at a constant, pre-set speed. 

 

I 

II

 

III

 

Min.

 

 

 

 

2-Variable differential pressure (

∆

p-v):

 

The setpoint value of the differential pressure H increases in a straight line between ½H and H 

within the permitted flow margin. The differential pressure generated by the pump is 

adjusted to the appropriate setpoint value of differential pressure.
