Piston pumps are precise and – compared to diaphragm dosing pumps – almost pressure-independent metering units. The flow rate changes in proportion to the stroke length and can thus be adjusted to very small values. Fields of application are – among others – process engineering and chemical processes, i.e.: wherever the medium must be metered precisely.
The FEDOS E / DX piston dosing pumps from Lutz-Jesco are available at flow rates between 0.17 and 31.5 l/h, with or without microprocessor control. Depending on the size of the pump, maximum pressures between 30 and 200 bar are admissible.
If no control is required for constant metering, the motor is connected directly to the terminal box. In this case, FEDOS E pumps are used. To change the flow rate, either the stroke length can be adjusted mechanically, or the speed of the motor is controlled by means of a separate frequency converter.
FEDOS DX pumps are used if an integration in controls or automatic control systems is requested.
FEDOS DX pumps allow the adaption to a large number of different control systems and system monitoring equipment. The signals required for the external avtivation of the pump can be simple voltage-free closing contacts from water meters or controllers or analog 0(4)...20 mA signals.

For the dosing of liquid chemicals, Alltech Dosieranlagen GmbH has developed the piston diaphragm metering pumps of the FKM series.
These metering pumps meet the highest requirements in operational reliability and accuracy.
Alltech piston diaphragm metering pumps are built in a modular concept. This guarantees high flexibility in combining the pump elements for various areas of applications.
By using different materials and designs for the liquid end, Alltech metering pumps may be used for the dosing of almost all kinds of chemicals.
To find an optimal solution for your dosing tasks, we offer various dosing capacities and pressure ranges.
The integrated pressure relief valve guarantees maximum security.
A wide range of accessories (stroke actuators, pulsation dampers e.g.) completes the range of our production.

The MultiFertic® dosing pump is a heavy duty, high precision electric or diaphrgam pump for dosing chemicals products and additives. It is made up of one driving module and 1 to 4 injection modules for 25 to 500 L/H (7.5 to 150 GPH).
In order to dose different products (INDEPENDENT INJECTION) or increase the inyection flow, several injection modules can be connected in the same injector. If we do so, we can obtain a higher flow regularity. In the case of 4 modules the injection flow is practically constant.

For corrosive and abrasive media, which have to be dosed against higher pressures than 16 bar piston pumps can be fitted with a piston-diaphragm system. The KMS system combines the advantages of leakage-free diaphragm dosing pumps and precise piston dosing pumps and thus ensures reliable dosing.
