They are used in those industries where there are increased requirements to hygiene, for example dairy production.

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.

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.

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.

General purpose pumps are widely used in all areas of industrial production around the world due to their gentle handling of the fluid during pumping, as well as their simple and robust design and minimal maintenance. Thanks to the standard connection dimensions, the pumps can be combined with any motor and other drive elements that comply with NEMA or IEC standards.

The AVA series pumps are designed and manufactured for use in the most critical applications, their main feature being that they are suitable for suction of contaminated gas mixtures, corrosive gases and vapours, explosive gases and vapours of any nature up to normal end vacuum, providing a maximum vacuum of up to 180 mbar. They are manufactured to the highest quality standards.

The AVPL oil rotary lobe pumps are extremely compact thanks to their integrated motor and transmission, making them the ideal choice for compact installations. They are equipped with extremely robust blades that ensure a long service life. Specially designed oil filters ensure excellent oil separation, removing even the smallest oil droplets from the exhaust air.

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.

Liquid ring vacuum pump systems designed to meet most needs of vacuum of the industry. Developed with one or more pumps acting in parallel depending on the specific needs, the systems are equipped with dedicated equipment for service liquid cooling and recirculation including instrumentation and devices for control and full remote automatic operation including control panel with PLC and VFD. Units for hazardous area, on request.

Heavy-duty gear pumps solve the toughest applications and ensure maximum flow rates when emptying large tanks. The foot-mounted design of the pump allows the use of various types of mechanical seals without changing the design of the pump itself (Universal Seal series). A large bearing cup located at the rear of the pump allows the installation of any seal, from a conventional stuffing box to a double mechanical seal.

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.

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.
