MS1
mechanical diaphragm pump
- flow range: 5.5-1200 liters/hour, maximum pressure 10bar
- contact end: PVDF, PVC, SS316L (pump head), PTFE (diaphragm), EPDM or FPM (sealing ring) and ceramic and stainless steel (valve ball)
- MS1 series mechanical diaphragm pump provides a variety of pump head material options, the motor can be equipped with frequency conversion and explosion-proof motor, stroke length can be manually adjusted, can also be equipped with electronic stroke regulator for automatic adjustment, so the application range is very wide.
- and the characteristics of the piston pump is not the same, MS1 series mechanical diaphragm metering pump is absolutely safe, no leakage, so the scope of application is wider than the piston pump.
- MS1 series mechanical diaphragm pump can be manually adjusted by the stroke adjustment knob, or the optional electronic stroke regulator can be automatically adjusted. This regulator can receive 4-20mA current signal and water meter digital pulse signal input.

Case Studies
Municipal Wastewater Treatment · SPRING MS1 — Application Case
Customer Profile
The typical setting in Municipal Wastewater Treatment is the inlet, biological and outlet stages of a municipal plant. The measuring point is SPRING MS1; the focus is mechanical high-pressure dosing with SPRING MS1.
Key Difficulties
Conditions are high solids and corrosive fractions, with large diurnal flow swings and, on top of that, effluent parameters drift and probes foul with sludge and biofilm, which a standard configuration cannot handle for long. The design therefore starts with configured by pressure class, flow and medium compatibility.
Implementation
The scope ran through the mechanical diaphragm series: selecting for mechanically driven continuous dosing. Technically it hinges on configured by pressure class, flow and medium compatibility, and on these requirements: stable compliance with Grade 1A discharge limits and online data reporting.
Customer Benefit
In practice this means stable continuous dosing at high pressure, with long service intervals, which cut the workload on the site maintenance team.
Food & Beverage · SPRING MS1 — Application Case
Project Background
The project covers dosing, pasteurising, filling and CIP stages. The work centres on SPRING MS1 and the core task is mechanical high-pressure dosing with SPRING MS1.
Operating Challenges
The medium and duty are characterised by syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. So SPRING MS1 cannot be specified generically — it calls for configured by pressure class, flow and medium compatibility.
Solution
The Ainstru engineering team worked through the mechanical diaphragm series: selecting for mechanically driven continuous dosing. The configuration involves configured by pressure class, flow and medium compatibility, with these requirements in view: food-safety and hygienic design per 3-A / EHEDG.
Results
Since start-up the system has run steadily; the practical result is stable continuous dosing at high pressure, with long service intervals.
Chemical & Pharmaceutical · SPRING MS1 — Application Case
Project Overview
The site is reactors, metering vessels and finished-product tanks. The customer wanted SPRING MS1 properly configured on the existing plant, with the aim of mechanical high-pressure dosing with SPRING MS1.
Technical Challenges
What actually causes trouble is highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. All of this means the SPRING MS1 configuration has to involve configured by pressure class, flow and medium compatibility.
Configuration
Supply and installation were organised through the mechanical diaphragm series: selecting for mechanically driven continuous dosing. On site this meant configured by pressure class, flow and medium compatibility, checked line by line against: Ex certification and GMP traceability of records.
Performance
After commissioning the outcome is stable continuous dosing at high pressure, with long service intervals, and the readings are now used for process tuning.
Power & Energy · SPRING MS1 — Application Case
Site Conditions
This is a Power & Energy customer whose plant is at boiler feedwater, turbine condensate and FGD/DeNOx systems. The main task was mechanical high-pressure dosing with SPRING MS1.
The Problem
The difficulty lies in high temperature and pressure with both steam and saline water; at the same time drift under high temperature and pressure, with very costly unplanned outages. Specification therefore means configured by pressure class, flow and medium compatibility.
What We Did
We took a mechanical diaphragm series approach — selecting for mechanically driven continuous dosing. Delivery was built around configured by pressure class, flow and medium compatibility, with point-by-point checks on: compliance with power-industry codes and unit availability targets.
Operating Outcome
In service the system performs as intended — stable continuous dosing at high pressure, with long service intervals, with routine maintenance falling noticeably.
