Pumps

General information about gear pumps

Gear pumps convey liquid media, which have at least minimal lubricating properties. The pumps can also be used for demanding media in combination with magnetic couplings.

General information about screw pumps

Screw pumps convey liquid media and are characterized by smooth running and protection of the pumped medium due to the continuous conveying movement. In conjunction with magnetic couplings, screw pumps can also be used for demanding media.

Application fields

• Lubricating oil pumps for generators, turbines, gearboxes, compressors and large engines
• Lubricating oil pumps for industrial plants (e.g. cement industry)
• Conveying pumps for chemicals and petrochemicals.
• Conveying pumps in the oil and gas industry
• Lubricating oil and fuel pumps in the marine industry

Advantages of screw pumps

• Suitable for a wide range of media
• Media-friendly pumping
• Very low pulsation
• Different technical variants available
• Operation in ATEX areas possible
• High efficiency
• Flat characteristic

Technical Features

• Delivery rates: 25 m³/h - 5000 m³/h
• Pressure feed pump: up to 280 bar
• Media temperature: up to max. 350 °C
• Viscosity medium: 1 mm²/s - 100,000 mm²/s
• Pump housing made of cast iron, steel or aluminum, tread coating possible as required
• Spindles made of case-hardened steel, surface coating possible as required
