GENERAL INFORMATION 

WHAT IS a condensate 

removal pump? 

WHY, how? 

Condensates (drops of water caused by warm, humid air passing over a cold 

surface) are formed in air conditioning, refrigeration and condensing boiler 

units. 

There are 2 ways of removing them 

It is a system which consists of a pump unit and a detection unit allowing 

condensates to be evacuated to a water drainage outlet where there is no 

gravity fall. 

This technology has 3 advantages: 

❶ It protects the appearance of the customer’s installation (no 

unsightly pipework). 

Gravity evacuation 

Evacuate the condensates 

by gravity, which means 

dealing with technical and 

aesthetic problems (distant 

drainage outlet, not enough 

fall, damage to walls and 

unsightly pipework). 

The removal pump 

1 2 

Or, install a condensate 

removal pump (smaller 

dimensions, the 

appearance of the 

installation is preserved, 

simple and quick to 

install, safer as equipped 

with alarm and 

non return valve). 

❷ Easy, simple and safe to install. 

❸ Reduction of the risk of bacterial contamination by waste water 

(no stagnation or back-flow of water due to non return valves) 

There are 3 types of condensate removal pumps:

General information

WHICH operating mode? 

Whether monoblock or compound type, condensate removal pumps 

operate in 3 different ways: 

The second 

is based on a float switch controlling 3 levels: 

❶ Reciprocating piston method 

These pumps are fitted with a piston which first draws in, then evacuates the 

condensate. 

❷ Centrifugal impeller method 

A centrifugal impeller evacuates the condensate. These pumps are intended 

for high flow rate requirements and are particularly suitable for contaminated 

condensates

1. On, 

2. Off, 

3. Alarm. 

➜ Fitted on piston pumps. 

❸ Peristaltic pumps 

A roller compresses a pipe which drives out the condensates (containing 

contaminates or not). These pumps are self-priming and can operate dry. 

WHICH detection system? 

SAUERMANN has developed 

3 detection systems: 

The first is based on two mechanical float switches 

one of which controls the On/Off levels and the 

other the Alarm. 

➜ Fitted on impeller pumps. 

As it is largely unaffected by the nature of the condensates (oil or grease on 

the surface, deposits of scale, dust or algae formation) float switch detection 

is very reliable. 

The presence of an alarm level leads to increased safety. 

As soon as a problem is detected (abnormally high water level leading to a 

risk of overflow), the pump automatically cuts off the air conditioning 

system compressor or triggers an audible or visual alarm. 

Problems may be caused by different reasons: 

- power cut 

- pump stoppage 

- pinched pipe 

3 

The third operates by detecting a temperature difference across the cooling 

coil of more than 6°C between two temperature sensors. 

➜ Fitted on PE 5100 peristaltic pumps.

YOU NEED TO KNOW 

THE FOLLOWING 

CHARACTERISTICS: 

❶ The volume of condensates 

produced or the refrigerating 

capacity of your installation 

will give you an indication 

of the volume of condensates 

to be removed. 

❷ The type of appliance 

which you are fitting it to. 

Choose your pump based 

on these characteristics. 

Check that the model 

you choose has 

a sufficient flow rate / 

pressure ratio.

Use the cooling capacity information supplied by the manufacturer of the air 

conditioner. It is generally estimated that, for normal usage conditions, the 

volume of condensates to be removed varies from 0.5 to 0.8 l/hr per kW of 

cooling capacity. This value may be doubled in very humid areas. 

For example: a cooling capacity of 3 kW will produce 

from 1.5 to 2.4 l/hr of condensates to be removed.

HOW TO INSTALL YOUR 


A few Basic Rules 

IMPORTANT NOTE ON 

COMMISSIONING PUMPS 

WITH REMOTE DETECTION 

Before installation, thoroughly rinse the coil 

and the condensates collection tank to 

remove any foreign bodies and metal 

particles. 

When the pump has a separate detection 

unit, it must be fixed horizontally on a 

support. 

Monoblock tank pumps must always be fitted 

horizontally on a support. 

Before carrying out 

any operation on 

the pump, make 

sure the installation 

is disconnected from 

the power supply. 

To ensure that the pumps function correctly in 

the future, ensure that when you first commission 

them (and after each maintenance operation) 

the pumps are properly primed. 

Check that the suction pipe (between the 

detection unit and the pump) and part of the 

discharge pipe are filled with water. 

Failure to observe these rules can lead to poor results (tank overflow, high 

noise level, abnormal overheating etc.) which are both inconvenient for the 

end user and costly for the installer. 

You can use the priming squeezie 

bottle ACC 00401. 

YOU ARE STRONGLY ADVISED TO AVOID THE USE OF DETERGENT OR AGGRES- 

SIVE PRODUCTS WHEN CLEANING THE TANK OF MONOBLOCK PUMPS

DETECTION UNIT INSTALLATION 

The vent pipe allows the air to be bled from the detection unit. You are advised 

to use the 4 mm clear tube supplied. Its length allows the upper level of the 

tube to be slightly above the maximum level of the condensates drain tank. In 

the event of a fault, this avoids overspill (principle of communicating vessels). 

When commissioning, ensure that this breather tube does not contain any 

water. 

Do not use a longer tube than the one supplied.

OPERATION 

INSTALLATION PE 5000 

Condensates are removed from the air 

conditioning unit at the tank outlet via a 

6 x 9 mm tube and the PE 5003 connector 

supplied with the pump. 

Pump operation is dependent on the operation of the air conditioning compressor 

or whenever the system provides cooling. The pump will continue to 

run for three minutes after the compressor has stopped.

Condensates are removed from the air 

conditioning unit at the tank outlet via a 6 

x 9 mm tube and the PE 5003 connector 

supplied with the pump. 

OPERATION 

The pump switches on when the temperature 

difference across the coil as measured 

by the two sensors is more than 6°C. 

The pump stops 3 minutes after the temperature 

difference falls below 6° C.

Carry out an in situ test 

and prime the pump. To 

do this, gently fill with 

water using the priming 

squeezie bottle (ACC00401). 

Press the test button on the PE 

5000 & PE 5100 to operate the 

pump for three minutes. 


The detection unit is connected to the 

condensate evacuation tube outlet or 

directly to the tank outlet. The pump is 

connected to the detection unit by a 6 x 

9 mm tube. 

OPERATION 

The pump operates when condensates 

enter the detection unit. In this configuration, 

a 230 V / 8 A NC alarm contact is 

available. 

MAINTENANCE PE 5000/ PE 5100 

PE 5200 

Replace the tube (PE 5002) at least every 

year and the pump head (PE 5001) every 

two years or as required. (Remove the 

4 screws, disconnect the connector and fit 

the new head). 

Very heavily contaminated condensates can be evacuated with this high 

flow rate pump and its 10 mm evacuation pipe. 

The accessory supplied (ACC 00601), to be secured in the condensate 

tank, switches the pump on and off. It can also be used as an alarm contact 

in the event of a tank overflow.
