Centrifugal Pumps-Magnetically Driven

Magnetically driven pumps are highly corrosion-resistant, making them suitable for handling corrosive fluids and chemicals such as acids, alkalis and saline solutions. Driven by synchronous magnet configuration, their seal-less, zero vapour loss prevents fluid leakage and the release of volatile, toxic and flammable chemicals. Available with ATEX certification, they offer a safe, reliable, energy-efficient and cost-effective solution. From compact pumps for low-duty applications to larger units for demanding services, our magnetically driven fluid handling solutions cover a wide range of requirements. Key features: • Capacity: duties from 1 m3/h up to 320 m3/h • Maximum pressure 16 bar • Zero vapour loss on hazardous liquids • ATEX certified for flammable liquids • No mechanical seals – reducing the risk of leakage • Motors from 0.12kW to 90kW • Handles up to 2% solids as standard, 30% with the solids handling mag drive • Maximum temperature up to 300°C • RunSafe SiC rotating bushes, axial thrusts and shafts for dry run protection • Close-coupled and long-coupled options • ISO 2858 and sub-ISO compliant Materials of construction: Metallic – stainless steel, Hastelloy C, exotic alloys Non-metallic – a ductile iron casing lined with Polypropylene, PVDF (Polyvinylidene Fluoride), ETFE (Ethylene Tetrafluoroethylene), PFA (PerFluoroAlkoxy) or Conductive PFA Moulded – Polypropylene, PTFE (Polytetrafluoroethylene), ETFE (Ethylene Tetrafluoroethylene) except for the moulded STN 70 which is contained within a ductile iron casing for extra rigidity and strength

Centrifugal Pump – ANSI Standard

This mag drive pump is designed to meet ISO and ANSI standards, making it suitable for various industries, including chemical processing, pharmaceutical and water treatment. Its seal-less design ensures zero vapour loss for hazardous liquids, a key advantage of all mag drive pumps. The DTN pump features an optional pump cartridge assembly, that can be easily installed easily in case of a breakdown, allowing for quick repairs without the need for a complete pump replacement. This reduces downtime and is cheaper than maintaining a spare pump. With ANSI standard dimensions, the DTN can be easily retrofitted into existing pump systems, resulting in substantial cost savings for companies looking to upgrade their equipment without modifying existing infrastructure. Its innovative impeller design and enhanced hydraulics contributes to improved efficiency and lower operating costs. Key features: • Zero vapour loss on hazardous liquids • Designed to ISO and ANSI standards • Handles toxic chemicals Material of construction: • ETFE (Ethylene Tetrafluoroethylene) – a cost-effective choice

Liquid Ring Vacuum Pumps & Systems

Liquid ring vacuum pumps are available in a wide range of metallurgies and sealing options to suit specific applications, including use in hazardous flammable and explosive areas. Their versatility and reliability means they are widely used in facilities of all sizes and across many industries. Available as single- or two-stage liquid ring units, these pumps can handle high volumes of vapours, condensable gases and liquids without compromising performance or mechanical reliability. The service liquid – water or other liquids, oils or solvents – can be selected to suit almost any application. When clean water is used, the aspirated air is ‘washed’ free of contaminants such as oil, carbon or plastics. Liquid ring vacuum pumps are designed for simplicity and reliability.
