SR series. A type
The A series dosing pumps are plunger pumps designed for dosing non-abrasive liquids.
They are characterised by a very wide range of materials for components that come into contact with the medium. Pumps in this series offer manual and automatic stroke adjustment and the option of a flushing or leak recovery system. The pump head mounting flange is open at the bottom and top and is equipped with covers to restrict access to the moving slide. The lower cover is equipped with a hose connection for collecting liquid in the event of leakage from the pump head due to wear of the seal or oil from the mechanism.
Doseuro A dosing pumps are also available in a high-pressure ‘HP’ version and are ATEX compliant.

Dosing of chemicals, including coagulants, fertilisers, acids, polymers, chemicals, etc. They can be used in applications such as:
Doseuro “A” series dosing pumps are plunger pumps designed for water treatment and industrial applications. They are reliable and easy to maintain, with the option of a flushing or leak recovery system.
“A” series spring return plunger dosing pumps are ideal for applications where:
Pumps are characterised by a very wide range of materials for components in contact with the medium. Pumps in this series also have the option of stroke adjustment both during pump operation and during downtime. Stroke adjustment can be performed manually or automatically using an automatic actuator driven by 4-20 mA; various BUS; or pneumatically.
The piston pump heads can be made in different material versions depending on the liquid being dosed. The pump head mounting flange is open at the bottom and top and is equipped with covers to restrict access to the moving slide. The lower guard is equipped with a hose connection for collecting liquid in the event of leakage from the pump head due to wear of the seal or oil from the mechanism.
Doseuro A dosing pumps are available in a standard version and a high-pressure ‘HP’ version. They also comply with the ATEX standard, allowing them to be installed in potentially explosive atmospheres.
