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.

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 16 bar. 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. The dosing quantity can be doubled by using two dosing heads. The largest motor-driven diaphragm dosing pump (Type GMR) has a hydraulically coupled double-diaphragm system.

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.

Stepper motor-driven diaphragm pumps are particularly suitable for highly accurate, reproducible industrial dosing thanks to their design. Many fluid media can be safely fed into the respective processes using these pumps.

The stepper-motor with its wear-free tooth belt drive, ensures a particularly homogeneous and gentle dosing process.

Piston dosing pumps are particularly precise dosing units, which are not dependent on pressure. Dosing capacity varies proportionally with the stroke length and can be set to the tiniest repeatable quantities. Two-piston and multiple-piston pumps are therefore particularly suitable for delivering precise mixtures, where different media must be mixed at a constant ratio which can be selected as desired. Using externally controlled drive motors, the total quantity can be varied from 5% to 100% at a constant ratio. Heated heads allow the dosing of media that are torpid when cold. A piston flushing skirt is available as an option, to prevent damaging leaks and protect the packing materials and pistons from abrasive chemicals.

Peristaltic pumps are the simplest types of dosing pumps. With their rotary displacement body, they are very maintenance-friendly and allow optimal dosing at low back-pressures for simple applications. Various performance classes are available, with different delivery capacities, back-pressures and control specifications.

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.
