Electromagnetic diaphragm metering pump

Sai GaoDeclineThe series is an Italian SEKO race high number explicitElectromagnetic diaphragm metering pumpIt is an upgraded iteration of the Tekna series, featuring high precision, intelligent control, long lifespan, and suitable for all scenarios of water treatment and chemical dosing. It is also a mainstream intelligent dosing pump in the industry. Sai GaoDeclineThere are five main control methods in the series

1、 5 core models (classified by control mode)

-EMS: Basic digital display model, manual button adjustment for flow, with backlit digital display screen, minimalist operation

-EML: Constant dosing version, dual adjustment of panel knob and button, supports liquid level protection, stable constant dosing

-EMC: Pulse signal type, receiving digital pulses from water meters, proportional linkage feeding, adapted to automation systems

-EMM: 4-20mA analog version, compatible with PLC/transmitter, 0-100% precise stepless adjustment

-EMG: versatile, compatible with pulse+4-20mA dual signals, suitable for complex working conditions

2、 Core performance parameters

-Flow range: 2.5~110L/h, covering all operating conditions

-Maximum pressure: 20 bar, suitable for high-pressure dosing scenarios

-Power supply: 100-240V wide voltage, 50/60Hz universal

-Stroke frequency: up to 300 times/minute, measurement accuracy ± 1%

-Protection level: IP65, waterproof and dustproof, suitable for harsh on-site environments

3、 Material and core advantages

-Standard liquid contact material: PVDF pump head+PTFE diaphragm+ceramic valve ball+EPDM/FPM sealing ring, acid and alkali resistant, corrosion-resistant, compatible with the vast majority of chemicals

-Ultra long lifespan: PTFE diaphragm comes with a 5-year factory warranty, eliminating the need for frequent replacement and resulting in extremely low maintenance costs

-Intelligent design: 2-line 8-bit backlit digital display, external signal interface (no need to disconnect wiring), with manual exhaust valve, low liquid level shutdown alarm

-Stable energy saving: adaptive power output, voltage fluctuations do not affect flow, lower energy consumption

4、 Typical application scenarios

-Water treatment: disinfection of tap water, addition of chemicals to swimming pools/cooling towers, addition of sewage flocculants, addition of reverse osmosis scale inhibitors

-Industry: High precision quantitative dosing for chemical additives, food and beverage, and pharmaceutical industries

-Environmental protection: precise dosing of wastewater treatment, exhaust gas desulfurization and denitrification agents

5、 High compatibility and reliability

The standard configuration adopts PVDF pump head and PTFE diaphragm, which is compatible with most chemicals used in industrial, sewage treatment, and drinking water fields.

Equipped with ceramic ball valves to further enhance the chemical stability and dosing reliability of the liquid contact end.

VI. Precise dosing and multiple control modes

Supports manual adjustment (via control panel buttons or knobs) and automatic control (via 4-20mA signal or pulse input) to meet different automation needs.

Provide liquid level probe interface (EML/EMC/EMM models), which can achieve low liquid level alarm and interlock protection.

7、 Easy installation and compact structure

Adopting a horizontal installation design, it can be directly fixed on the dosing bucket, saving space.

The pump body is lightweight (such as the EMS803 model weighing only 4.4 kg), making it easy to handle and integrate.
