Description
The Seko TPG803 Digital Dosing Pump is a high-performance, solenoid-driven chemical dosing pump designed to provide accurate and reliable dosing for demanding water treatment and industrial applications. Suitable for drinking water treatment, wastewater treatment, swimming pools, cooling towers, agriculture, and industrial process control, the TPG803 offers precise chemical injection with both constant and proportional dosing modes.
The pump features a digital controller that allows either manual constant-flow dosing or proportional dosing using an external 4–20 mA analogue signal or a digital pulse input, such as a water meter. This flexibility makes the TPG803 ideal for applications requiring accurate chemical dosing based on changing process conditions.
Manufactured with a PVDF pump head as standard, the TPG803 provides excellent chemical resistance and compatibility with a wide range of treatment chemicals. An AISI 316L stainless steel pump head is also available for applications requiring enhanced chemical compatibility.
Each pump is supplied with a complete installation kit and includes a manual priming function for quick commissioning and reliable operation.
