Description

The Seko Tekna APG603 Analogue Proportional Dosing Pump is a high-precision solenoid-driven chemical dosing pump designed to provide accurate and reliable chemical dosing for a wide range of water treatment and industrial applications. Ideal for water purification, wastewater treatment, swimming pools, cooling towers, agriculture, and industrial process control, the APG603 offers both constant-flow and proportional dosing to meet varying process requirements.

The pump features easy-to-use analogue controls with manually adjustable constant flow, as well as proportional dosing based on either a 4-20 mA analogue signal or an external digital signal from a water meter. A six-position selector switch allows quick selection between constant dosing, proportional dosing, multiplication mode, and division modes, providing exceptional flexibility for a wide range of dosing applications.

Manufactured with a PVDF pump head as standard, the APG603 offers outstanding chemical compatibility with a wide range of treatment chemicals. A PVC pump head is also available on request for suitable applications.

Each pump is supplied with a complete installation kit, making it ready for installation in residential, commercial, and industrial water treatment systems.
