Low-noise pumps

The vertical centrifugal pump is designed to submerge the pump in the pumped liquid so that the electric motor remains above the liquid level. The semi-submersible chemical pump uses special construction materials and technical solutions that allow it to withstand chemical attack not only from the inside but also from the outside. We offer sealed semi-submersible vertical pumps with magnetic coupling and pumps with mechanical seal for pumping sodium hydroxide and hypochlorite, sulfuric, hydrochloric, nitric acid, alkalis, various corrosive mixtures, solvent, wastewater with chemical impurities, etc.

The AVM and AVL series consist of single-stage liquid ring vacuum pumps designed to achieve deep vacuum. Both series have the same hydraulics but different designs.

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 design of the pumps allows them to be used for many different applications. The standard design includes an enlarged rectangular inlet hopper with a screw conveyor that pushes the product to be pumped into the pump's working section. There are versions in which the pump inlet is equipped with a large screw, an integrated cork breaker or both. Most pumps are supplied in a monoblock design (direct connection of the pump to the electric motor) or with a free shaft outlet (without an electric motor).

The hygienic screw pumps are specially designed for use in the food, cosmetics and beverage industries. The pumps have a simple design, which greatly simplifies their cleaning.

The pumps themselves are made of high-quality materials, have a robust design and are maintenance-free.

The Valisi VD-ECA series are diaphragm and piston metering pumps with advanced metering control for precise and automatic control. The pumps are designed to accommodate a variety of remote control options such as SCADA, etc.

AVVS series consists in dry screw vacuum pumps designed tooperate at very deep vacuum capable to achieve 0,05 mbar or deeper if combined with a booster pump. The new patented hybrid screw design ensures higher efficiency due to lower temperature and less power consumption. Different type of coatings protect the internals from corrosion caused by aggressive gas mixture and vapors typical of the process industry, chemical, pharmaceutical and petrochemical applications.

Liquid ring vacuum pumps and systems meeting API 681 standards for chemical and petrochemical applications. Suitable for heavy duties, are available in different exotic materials with single or double cartridge API 682 cartridge mechanical seals. Package design standards in line with most stringent project specifications and quality requirements.

Liquid ring vacuum pumps are used in centralised vacuum systems and in power generation. The vacuum systems consist of exhaust ventilation units for the main condenser and filling units for the water condenser. The systems are designed for both load and hold modes.
In many cases, the pump is assisted by a first stage gas or steam ejector to improve pump performance at different condenser loads. The ASCO VACUUM team has extensive experience in geothermal applications.

Hybrid systems offer the engineering advantage of designing process vacuum systems based on a combination of two or more different technologies to achieve the required performance with the most reliable and efficient solution.

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 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.

The SP series plastic centrifugal sealed chemical pumps with magnetic coupling are ideal for pumping aggressive liquids, various corrosive mixtures, solvent, wastewater with chemical impurities. The concentration of suspended solids should be no more than 1.25 mg/cubic cm. All pump components in contact with the medium are free of metal parts. Thus, no oxidation of the medium occurs in these pumps. The pumps are used even for media where contact with the atmosphere is not permitted.

Peristaltic pumps of the N series (roller design) are self-priming peristaltic pumps with a seal-free design. The liquids are transported inside the hose and do not come into contact with any metal parts of the pump.
