MS1A064B31A4080 Spring SEKO Mechanical Diaphragm Pump
- Flow range: 8 l/h, max. pressure 10 bar
- Wetted materials: PVC (pump head), PTFE (diaphragm), FPM (seal) and ceramic (valve ball)
- The MS1 series mechanical diaphragm pumps offer a variety of pump head materials. The motor can be optionally equipped with variable frequency and explosion-proof versions. The stroke length can be adjusted manually, or an electronic stroke adjuster can be optionally selected for automatic adjustment, making the application range very wide.
- The flow rate of the MS1 series mechanical diaphragm pumps can be adjusted manually via the stroke adjustment knob, or an electronic stroke adjuster can be optionally selected for automatic adjustment. This adjuster can receive 4-20 mA current signal and water meter digital pulse signal inputs.
