Jesco Dosing Pumps

Jesco dosing pumps are reliable, flexible pumps that are capable of dosing at very low or high flow rates, in extreme temperatures, and in challenging environments. Dosing pump models include:

  • Leak free Solenoid-Diaphragm Dosing Pumps and Motor-driven Diaphragm Dosing Pumps for highly aggressive or toxic media
  • Heavy-duty hydraulically actuated tubular diaphragm pumps for high capacities and pressures
  • Stepper motor-driven diaphragm pumps for highly accurate, reproducible industrial dosing
  • Precise Motor-driven Piston Dosing Pumps that are not dependent on pressure
  • Simple Peristaltic Pumps for optimal dosing at low back-pressures

Solenoid-Diaphragm Dosing Pumps

Diaphragm dosing pumps are leak-free, and are therefore suitable for highly aggressive or toxic media. Depending on the gear type, the diaphragm allows pressures up to 232 psig.

Diaphragm dosing pumps are fitted with a separation chamber as standard. If a crack forms in the diaphragm due to wear, this prevents the medium from flooding the system components or the pump itself. The medium is controlled and flows through a downpipe to the collecting basin. The medium sides of the diaphragms are coated with PTFE.

Magdos Pump L-Series: LB, LD, LK, LP, LA

The solenoid-driven diaphragm dosing pump MAGDOS is the most versatile dosing pump – right for most applications.

All pumps of the MAGDOS L series are certified according to UL and CSA. The power ranges cover from 0.36 to 15 l/h with back pressures up to 16 bar. Double-ball valves ensure exact dosing. The dosing power can be adapted by varying the stroke frequency manually, via an external control contact or using a 0/4 – 20 mA signal.

Several different materials and connections are available for dis- charge and suction side, depending on the specific applications. Accessory sets consisting of a hose, injection nozzle and suction line are available to enable optimal results and quick installation. Ethernet IIoT is also available.

Motor-driven Diaphragm Dosing Pumps

The largest motor-driven diaphragm dosing pump (Type GMR) has a hydraulically coupled double-diaphragm system.

Hydraulically Actuated Diaphragm Pumps

Heavy-duty hydraulically actuated tubular diaphragm pump designed for high capacity and high pressures. Also ideally suited for corrosive liquids such as H2SO4 or slurries.

The simple, yet unique vertical hydraulics eliminates need for complicated vent and refill mechanisms. Prestressed tubular diaphragm handles inconsistent suction conditions and suction lift capabilities to 16 feet.


Dosing Pump Accessories

Lutz-Jesco offers a complete range of technically mature suction-side and pressure-side accessories for the dosing of fluids.

This range is designed for Lutz-Jesco dosing pumps and allows the modular assembly of the components needed for a complete dosing system.


Due to their simplicity of use and reliable properties, chlorine and chlorine compounds have been used successfully in water treatment for decades.

Our gas-conveying technology is specially designed for chlorination. However different the requirements are, our comprehensive range of well-proven units can deliver doses of chlorine gas under vacuum, or liquid chlorine compounds.

With their matching components, from chlorine dosing to analysis and warning devices, Lutz-Jesco chlorination systems meet all the modern system requirements. They are distinguished by their reliability and repeated dosing accuracy. 

Dry Feeder

Besides equipment for the precise dosing of liquid and gaseous media, Lutz-Jesco offers dry dosing units, along with the related accessories for building a complete dosing installation. Lutz-Jesco dry feeders work by volume, i.e. the weight of the dosing material is not considered. They are self-supporting, welded structures made with stainless steel sheet, and they are available with various delivery capacities.

Measuring and Control Equipment for Metering

In many cases, dosing control measurements are required, for example water values, and uninterrupted transmission of the measurement values. The next requirement is for regulator functions, or controls for the dosing units. Lutz-Jesco has a wide range of equipment to meet these requirements:  fittings, sensors, measuring cells, signal amplifiers, signal generators, measuring devices and regulators.

Disinfection Systems

As water consumption increases, the need for water treatment systems focused on recycling becomes more acute.  Lutz-Jesco systems are designed to DIN standards and promise optimum water quality through precisely measured disinfection. We utilize our specialized knowledge and decades of experience to find the best  technically and scientifically sound solution for you.
