Xieke Advantage Supply Keller DMP-20/75SNN Diaphragm Pump

Xieke Advantage Supply Keller DMP-20/75SNN Diaphragm PumpIt is a precision fluid conveying equipment designed for industrial scenes. With core characteristics such as low pulsation, high sealing, strong corrosion resistance, and long service life, it is widely used in industries such as chemical, environmental protection, pharmaceutical, semiconductor, laboratory, and food and beverage. It is an upgraded and preferred alternative to traditional mechanical pumps/metering pumps.

Xieke Advantage Supply Keller DMP-20/75SNN Diaphragm PumpHas the following technical characteristics

stable output

Optimize the cavity structure and diaphragm stroke design, with a pulsation rate of ≤ 3% and a flow repeatability of ± 1%, to meet the requirements of precision dosing and circulation

Strong corrosion resistance

The pump head/channel can be made of PTFE, PFA, 316L, FFKM and other material combinations, compatible with strong acids, strong bases, organic solvents and high-purity media

zero-leakage seal

Fully enclosed double diaphragm+pneumatic/electric isolation structure, preventing medium overflow and cross contamination, in compliance with GMP/environmental emission requirements

Low maintenance operation

No shaft seal design, minimal wear and tear parts; Operating noise<65dB, supporting 7 × 24-hour continuous operation, MTBF＞15000h

Intelligent compatibility

Standard 4-20mA/RS485 interface, supports seamless integration of PLC/DCS/SCADA systems, and can achieve remote start stop and status monitoring

DMP-20/75SNN is not an ordinary diaphragm pump, but a professional equipment optimized for medium and low pressure, medium and small flow, and high-precision requirements

Low pulsation smooth conveying

Adopting a double diaphragm symmetrical structure design, coupled with optimized airflow distribution valve, significantly reduces output pulsation (pulsation rate<5%), ensuring continuous and uniform fluid flow, especially suitable for dosing and sampling processes that require high flow stability.

Strong self-priming ability, safe dry operation

It has excellent self-priming performance (up to 3-5 meters of water column), allowing for short-term dry operation without damaging the pump body, greatly improving the safety of the system during the start stop phase or liquid level fluctuation conditions.

Leak free sealing structure

The fully enclosed pneumatic drive chamber is isolated from the medium chamber to eliminate the risk of shaft seal leakage, comply with environmental emission standards, and prevent the overflow pollution of toxic, harmful, and valuable media.

Low energy silent operation

Pneumatic efficiency optimization design, with air consumption 15% -20% lower than similar competitors; Control the operating noise below 65dB (A) to improve the working environment in the workshop.

Wide range adjustment capability

By adjusting the intake pressure or installing a throttle valve, the flow rate can be continuously adjusted from 0 to 100%, with fast response speed and adaptability to automated control systems.

Application scenarios

Chemical reactor feeding and circulating transportation

Accurate dosing for sewage treatment/flue gas desulfurization

High purity distribution of semiconductor cleaning solution/photoresist

Pharmaceutical aseptic filling and CIP cleaning circuit

Laboratory analytical instrument supporting liquid supply system
