Description
Metering pump, wall mount, 20 l/hr @ 4 bar, PVDF head with Viton seals for chlorine and acidic chemicals, fixed stroke length, manual adjustment via potentiometer, includes installation kit
The EMEC TCO 04-20-VF is an entry-level electronic chemical dosing pump designed for simple and reliable chemical injection in low to moderate pressure applications. Part of the EMEC T Series, it provides constant dosing with easy manual control, making it ideal for straightforward dosing requirements.
With a maximum output of 20 L/hr at 4 bar, this pump is well suited for water treatment, disinfection, and general chemical dosing applications where consistent performance is required. The dosing rate is easily controlled via a front-mounted potentiometer, allowing for quick adjustments during operation.
The pump features a durable PVDF pump head combined with Viton (VF) seals, offering excellent resistance to chlorine and other aggressive chemicals. A high-resistance diaphragm ensures long service life and dependable operation, even under continuous use.
Its compact, wall-mounted design enables easy installation and integration into existing systems, making it a practical and cost-effective solution for entry-level dosing applications.

EMEC TCO Electronic Chemical Dosing Pumps
The EMEC TCO Series is a range of electronic solenoid-driven dosing pumps designed for precise and reliable chemical injection in water treatment, agriculture, and industrial applications. Unlike water-powered injectors, the TCO range uses an electric motor and adjustable stroke/speed control to accurately dose chemicals, making it ideal for systems requiring consistent dosing regardless of water flow.
The TCO Series is commonly used in chlorination systems, water treatment plants, pools, irrigation dosing, and industrial processes where controlled chemical injection is critical. With durable construction, simple adjustment, and consistent performance, EMEC TCO pumps provide a dependable solution for accurate dosing in both continuous and controlled environments.

How an EMEC Solenoid Pump Works
An EMEC solenoid dosing pump works by using an electromagnetic coil (solenoid) to drive a piston or diaphragm back and forth in rapid strokes.
When the solenoid is energised, it pulls the diaphragm inward, creating suction that draws chemical into the pump head through an inlet check valve. When the coil de-energises, a spring pushes the diaphragm outward, forcing the chemical through an outlet check valve and into the dosing line.
The dosing rate is controlled by adjusting the stroke frequency and/or stroke length, allowing precise and consistent chemical injection regardless of changes in water flow or pressure.
