Pumps and mixers for the chemical industry, water treatment and environmental protection

In the chemistry and environmental protection sector, equipment operates with the most aggressive substances – acids, alkalis, solvents, and toxic compounds. There is no room for compromise here: an unsuitable material, seal failure, or inaccurate dosing can mean an accident, environmental pollution, or production downtime. UAB Aisteris supplies chemically resistant pumps and mixers that reliably operate in the most demanding conditions – for chemical plants, water treatment facilities, and environmental companies in Lithuania and the Baltic states.

Applications in the chemistry and environmental sector

Our equipment is used in the following chemical and environmental applications:

Pumping and dosing of acids, alkalis, solvents and chemical products in chemical factories
In water treatment plants – reagent dosing, sludge pumping, filtrate and percolate
In waste management companies – pumping of liquid waste, sewage and chemically contaminated liquids
Environmental projects – soil and groundwater treatment systems
In laboratories and research centres – precise reagent dosing and sample pumping

Our range for the chemistry and environmental sector

We represent manufacturers whose equipment is designed to work with the most aggressive chemicals.

Verder – Peristaltic and Diaphragm Pumps for Aggressive Media

Verderflex peristaltic pumps – the ideal choice for the chemical sector, where the fluid must not come into contact with metal or seals. The fluid only comes into contact with the chemically resistant hose (natural rubber, EPDM, Hypalon, NBR or others), so even the strongest acids or alkalis do not damage the pump mechanism. Verderair pneumatic diaphragm pumps are suitable for explosive ATEX zones and locations without electricity. Verderpetra diaphragm pumps – for high-pressure applications and filtration.

Debem – Chemical-resistant dosing pumps

Dosing pumps made of PVDF, PP and PTFE materials – the standard choice for chemical laboratories and plants, where accuracy and chemical resistance are paramount. Diaphragm and peristaltic models ensure precise dosing even with concentrated acids, alkalis, and oxidisers. Debem pumps are used in water treatment plants across Europe – especially for dosing coagulants and disinfectants.

Visco Jet – mixers for chemical tanks and reactors

Visco Jet stainless steel and chemically resistant mixers are suitable for chemical reactors, neutralisation tanks, and reagent preparation systems. IBC mixers allow for efficient mixing of chemicals in standard 1000-litre containers, while stationary mixers are for continuous processes. Visco Jet mixers comply with ATEX requirements for explosive areas.

Materials science – why is it important?

In the chemical sector, the selection of materials for pumps and mixers is as important as technical parameters. Incorrect materials can mean rapid corrosion, contamination, or failure. The equipment we supply is available with the following housing and wetted part options:

PP (polypropylene) - widely used for acids and alkalis up to certain concentrations
PVDF (polyvinylidene fluoride) – excellent chemical resistance, suitable for highly concentrated acids
PTFE (teflon) – highest chemical resistance, suitable for almost all chemical substances
AISI 316L stainless steel – suitable for many process fluids and meets pharmaceutical/food requirements
