Oil-free pumps

Pneumatic diaphragm pumps of the hygienic series are made of polished stainless steel AISI 316L. The pumps are hermetically sealed, self-priming, and are designed primarily for pumping of slightly aggressive media, food and cosmetic products. They are used in those industries where there are increased requirements to hygiene, for example dairy production.

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.

Designed for use in the most extreme chemical processing applications, the ULTRAChem® series pumps are magnetically driven pumps that meet ANSI standards. The pumps are designed for pumping aggressive, chemically active liquids. The concentration of suspended solids should not exceed 1.25 mg/cubic cm. The pumps are ideal for operation at ultra-low ambient temperatures.

Dry operated rotary vane pumps designed to operate without any lubrication. They require minimum maintenance, which can be carried out easily thanks to the direct access to the vanes. They can be used as vacuum pumps, as compressors, or to produce vacuum and pressure simultaneously.

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 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.

The SANDPIPER Non-Metallic AODD Pumps for standard applications are one of the most popular diaphragm pump series. The pumps are available in a wide range of sizes (1/4'' - 3''), casing materials and elastomers. The pumps are most commonly used in production areas where aggressive and explosive liquids need to be pumped. Due to their light weight, these pumps are used in portable versions for pumping liquids from drums.

DELLMECO air-operated diaphragm pumps (AODD) are suitable for a wide range of applications. They have high abrasion resistance and can withstand aggressive chemicals, including acids, oils, solvents, paints, sludge and even media containing solid particles, such as in wastewater. These pumps can also be used for pumping powders.
All pumps are self-priming and their performance and pressure can be easily controlled. This pump is a positive displacement pump that pumps liquids by the movement of diaphragms driven by compressed air. The casing in contact with the liquid is made of polyethylene (PE), polyethylene conductive, polytetrafluoroethylene (PTFE), polytetrafluoroethylene conductive.

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.

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.

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.

Valisi metal pumps of the V series are available in a variety of construction materials: aluminium and stainless steel. This series of pumps for industrial applications provides high efficiency and reliability for continuous operation. With a flow rate of up to 908 l/min and a wide variety of materials and channel configurations, you will find the right pump for your application. FDA-compliant metal pumps are available, specially manufactured from materials that are safe for food, beverage, pharmaceutical and cosmetic processes where 3A, USDA or EHEDG standards are not required. The simple, robust design features trouble-free air valve operation, oil-free operation, reliable on/off operation, easy operation and maintenance, and delicate/shear-sensitive product handling. The pumps comply with EU Directive 1935/2004.

Сlose coupled industrial pumps of the NCL series - IN LINE design - are units designed to support technological processes involving the pumping of hazardous liquids. The main field of application of such equipment is the petrochemical and chemical industries. The pumps are indispensable for solving such tasks as pumping acids, caustics, chlorine alkaline solutions, chemical fibers, polymers, volatile organic compounds, sludge pumping and waste treatment. The pumps are CE-marked and comply with applicable European directives such as ATEX.

The EL series pumps are designed for pumping liquids containing solid particles. The axial impeller is resistant to wear in contaminated media.

Side channel self-priming stainless steel pumps - MX series. It is a liquid ring pump, completely made of Stainless Steel 316, self-priming and reversible.

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.

The MENC-INOX industrial pumps are pumps with a flexible stainless steel impeller. The impeller deforms inside the stainless steel casing to provide fast suction of up to 5 m and constant and accurate liquid transfer. In addition, the low speed makes this pump suitable for pumping liquids and media containing solids that require careful handling. Due to the low speed, pumping is carried out without harmful foaming of the emulsion, the so-called "shear effect".
