Komba Serieselectromagnetic diaphragm metering pump
Komba series is a microprocessor-controlled digital display electromagnetic diaphragm metering pump with simple and stable operation. Includes 4 sub-families: DMS,DML,DMC and DMM.
main features:
- maximum flow: 9 L/H, maximum pressure: 10 Bar
compatibility:
- PVDF pump head and ceramic ball valve as the standard configuration of the pump
- PVDF pump head is compatible with all chemicals used in industry, sewage treatment and drinking water; the use of ceramic ball valves improves the reliability of dosing and the chemical compatibility of the entire liquid contact end.
reliable performance:
- After inspection, the service life of the diaphragm exceeds 5 years. Advanced design concept and excellent manufacturing process, resulting in the long service life of the diaphragm diaphragm is made of pure solid PTFE material, can be compatible with most chemicals.
dosing mode:
- flow can be adjusted manually or automatically (signal input control). DML,DMM and DMC also have a liquid level probe interface and manual exhaust valve, which can assist in starting the pump.
touch liquid end material:
- pump head: PVDF
- valve ball: Ceramic
- sealing: FPM/EPDM
- diaphragm: PTFE
Installation method:
- Horizontal installation

Case Studies
Municipal Wastewater Treatment · KOMBA — Application Case
Application Context
the inlet, biological and outlet stages of a municipal plant is a typical Municipal Wastewater Treatment duty. The project started from KOMBA, focusing on compact solenoid diaphragm dosing with the KOMBA range.
Process Constraints
effluent parameters drift and probes foul with sludge and biofilm, and high solids and corrosive fractions, with large diurnal flow swings only amplify it. The KOMBA specification must therefore cover sized by installation space, dosing rate and level-signal interface.
Delivery Approach
Delivery was handled as the solenoid diaphragm series — selecting for solenoid-driven diaphragm dosing behaviour. Execution centred on sized by installation space, dosing rate and level-signal interface, together with stable compliance with Grade 1A discharge limits and online data reporting.
Field Results
Operation shows the benefit clearly — small footprint, easy to add in retrofit projects, with confidence in this measuring point improving markedly.
Food & Beverage · KOMBA — Application Case
Customer Profile
The typical setting in Food & Beverage is dosing, pasteurising, filling and CIP stages. The measuring point is KOMBA; the focus is compact solenoid diaphragm dosing with the KOMBA range.
Key Difficulties
Conditions are syrups, dairy and beverages that scale easily, under strict hygienic requirements and, on top of that, frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, which a standard configuration cannot handle for long. The design therefore starts with sized by installation space, dosing rate and level-signal interface.
Implementation
The scope ran through the solenoid diaphragm series: selecting for solenoid-driven diaphragm dosing behaviour. Technically it hinges on sized by installation space, dosing rate and level-signal interface, and on these requirements: food-safety and hygienic design per 3-A / EHEDG.
Customer Benefit
In practice this means small footprint, easy to add in retrofit projects, which cut the workload on the site maintenance team.
Chemical & Pharmaceutical · KOMBA — Application Case
Project Background
The project covers reactors, metering vessels and finished-product tanks. The work centres on KOMBA and the core task is compact solenoid diaphragm dosing with the KOMBA range.
Operating Challenges
The medium and duty are characterised by highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. So KOMBA cannot be specified generically — it calls for sized by installation space, dosing rate and level-signal interface.
Solution
The Ainstru engineering team worked through the solenoid diaphragm series: selecting for solenoid-driven diaphragm dosing behaviour. The configuration involves sized by installation space, dosing rate and level-signal interface, with these requirements in view: Ex certification and GMP traceability of records.
Results
Since start-up the system has run steadily; the practical result is small footprint, easy to add in retrofit projects.
Power & Energy · KOMBA — Application Case
Project Overview
The site is boiler feedwater, turbine condensate and FGD/DeNOx systems. The customer wanted KOMBA properly configured on the existing plant, with the aim of compact solenoid diaphragm dosing with the KOMBA range.
Technical Challenges
What actually causes trouble is high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. All of this means the KOMBA configuration has to involve sized by installation space, dosing rate and level-signal interface.
Configuration
Supply and installation were organised through the solenoid diaphragm series: selecting for solenoid-driven diaphragm dosing behaviour. On site this meant sized by installation space, dosing rate and level-signal interface, checked line by line against: compliance with power-industry codes and unit availability targets.
Performance
After commissioning the outcome is small footprint, easy to add in retrofit projects, and the readings are now used for process tuning.
