Wetted materials: PVDF (pump head), PTFE (diaphragm), EPDM (seal), ceramic (valve ball)
MS1A064A44A4080 Spring SEKO mechanical diaphragm pump
- Flow range: 5.5 l/h, max. pressure 10 bar
- Wetted materials: PVDF (pump head), PTFE (diaphragm), EPDM (seal) and ceramic (valve ball)
- The MS1 series mechanical diaphragm pump offers a variety of pump head materials. The motor can be optionally equipped with variable frequency and explosion-proof motors. The stroke length can be adjusted manually, or an electronic stroke adjuster can be optionally selected for automatic adjustment, making its application range very wide.
- The flow rate of the MS1 series mechanical diaphragm pump can be adjusted manually via the stroke adjustment knob, or automatically via an optional electronic stroke adjuster. This adjuster can receive 4-20 mA current signals and digital pulse signals from water meters.
