Verder

Verder is a Dutch-founded international engineering group specializing in pump technology, with its liquids division, Verder Liquids, designing and manufacturing peristaltic hose pumps, industrial process pumps, and the Verderair range of air-operated double diaphragm (AODD) pumps for transferring aggressive, abrasive, and viscous fluids. Verder pumps are built for chemical, wastewater, mining, pharmaceutical, food, and general industrial transfer duties, offering metallic and non-metallic wetted-part construction to match a wide range of chemical compatibilities. The Verderair diaphragm pump series is known for fast-acting air valve technology that reduces compressed-air consumption while maintaining reliable self-priming, dry-run-safe operation with no seals or packing to wear out. Seven Star LLC is an authorized supplier of genuine Verder and Verderair pumps and spare parts throughout Oman and the GCC, supporting industrial plants with reliable fluid transfer solutions and responsive local technical backup.

Frequently Asked Questions

How do Verderair diaphragm pumps handle abrasive or chemically aggressive fluids?
Verderair air-operated double diaphragm pumps are available in metallic (aluminium, stainless steel) and non-metallic (polypropylene, PVDF) wetted-part construction, with diaphragm and seat materials such as PTFE, Santoprene, and Buna-N selected to match the fluid chemistry, allowing safe transfer of slurries, solvents, and corrosive process fluids.
Can Verderair pumps run dry without damage?
Yes, air-operated double diaphragm pumps in the Verderair range are inherently dry-run safe because they have no mechanical seals or packing glands that depend on the pumped fluid for lubrication, making them tolerant of intermittent dry running during tank changeovers.
Are Verder pumps suitable for ATEX or hazardous area installations?
Select Verderair models are offered in ATEX-certified configurations for use in classified hazardous zones, using pneumatic actuation rather than electrical power at the pump head, which suits refineries and chemical plants handling flammable liquids.
What industrial applications typically use Verder diaphragm pumps?
Typical applications include chemical dosing and transfer, wastewater and sludge handling, drum and IBC emptying, mining slurry transfer, and general industrial fluid transfer where self-priming, low-shear operation is needed.
Does Seven Star LLC supply genuine Verder pump spare parts in Oman?
Yes, Seven Star LLC is an authorized supplier of genuine Verder and Verderair pumps, diaphragm kits, and repair parts across Oman and the GCC, with technical support for pump selection and maintenance.
