Pumps for Alkalis

Despite their simple design and operating principle, Valisi plastic diaphragm pumps are characterised by exceptional performance and reliability. They can be used to pump clean liquids with low viscosity as well as abrasive liquids with medium viscosity. In addition, these pumps can handle large particles without damaging the equipment. And thanks to the pneumatic motor, they can be used in explosive atmospheres.

The modern metal  diaphragm pump of VC series features a unique, non-jamming air valve that is simple, robust and reliable, and does not require a separate or mechanically operated pilot valve. The bolted design ensures leak-free pumping of liquids. The pneumatic diaphragm pumps are designed and manufactured to meet the needs of both OEMs and end users. The main characteristics of these pumps are competitive prices, few parts, simple design and maintenance, and high quality. Stainless steel pumps are FDA approved. Aluminium pumps with PTFE diaphragms are explosion-proof and ATEX certified.

Idrochemical NCM centrifugal pumps comply with the dimensional criteria of ISO 2858 and ISO 5199. The casing and impeller profiles are designed to achieve high hydraulic efficiency and low NPSH.

The NCM line is available in five bearing housing sizes with wide interchangeability of parts, which allows for low maintenance spares.

With pump ends conforming to ISO 2858 dimensional and technical standards and to ISO 5199 design criteria, the NCB provides a compact, space-saving arrangement ideal for industrial processes or installations when space is at a premium. NCB pumps are fitted with standard, readily available electric motors so the user can choose an enclosure to suit the application.

Heavy-Duty Casing with integral foot and multi-ribbed discharge flange provides superior resistance to pipe loads.

CMA series pumps are open impeller pumps designed for pumping liquids with suspended solids and solid particles. CMC series pumps are pumps with a closed impeller made of two stainless steel disks. CMA/CMC series pumps are used for transportation of large volumes of chemically active liquids and acids, for petroleum products, in galvanizing, pharmaceutical and paint and varnish industries.

The pumps are used in various enterprises, industries, in the most difficult operating conditions, ensuring smooth fluid transfer. The pumps are suitable for pumping liquids with low and high viscosity, as well as for pumping abrasive, sticky, crushing and foaming liquids. The pumps are particularly suited for handling products with solid particles. The suction capacity is max. 5m/s. The pumps deliver regular, linear, pulsation-free and measured flow. Quiet operation without vibration.

The non-self-priming plastic centrifugal hermetic chemical pumps with magnetic coupling of the DB series are one of the most popular chemical pumps in the pump segment with a capacity of up to 50 m3/h. The pumps are ideal for pumping aggressive liquids such as sodium hydroxide and hypochlorite, sulfuric acid, hydrochloric acid, nitric acid, alkalis, various corrosive mixtures, solvent, wastewater with chemical impurities. The concentration of suspended particles should not exceed 1.25 mg/cubic cm.
