Verderflex Rapide Peristaltic Hose Pump
Overview
The Verderflex Rapide pump is a compact, industrial-grade peristaltic hose pump engineered by Verder for continuous duty in chemical dosing, effluent transfer, and abrasive-slurry applications where seal-less, valve-less operation is a requirement rather than a convenience. Assembled around a heavy-duty aluminium housing and an IP55-rated gearmotor, the Rapide range delivers flow rates up to roughly 1.67 GPM per head and discharge pressures up to 2 bar (29 PSI), with standard hose bores up to 12 mm (0.5 in) and a maximum operating temperature of 85°C (185°F). Because the pumped fluid only ever contacts the inner bore of a single replaceable hose or tube, the Verderflex Rapide pump eliminates the mechanical seals, check valves, and glands that are typically the first point of failure in centrifugal or diaphragm alternatives.
As the official authorized partner and exclusive regional representative for Verder in Oman, Seven Star LLC proudly supplies the Verderflex Rapide peristaltic hose pump to water treatment plants, chemical processors, and industrial facilities across the Sultanate of Oman and the wider GCC. Every unit is shipped with genuine Verderprene or silicone hose elements, full FDA and USP-compliant documentation where applicable, and local commissioning support from our Muscat-based technical team, giving buyers in Muscat, Sohar, and Salalah a dependable regional source for both the pump and its consumable hose kits.
Operating Principle
The Verderflex Rapide pump works on the peristaltic principle: a rotor fitted with rollers or shoes progressively compresses a flexible hose against the inner wall of the pump casing, creating a moving occlusion zone that pushes fluid ahead of it while drawing fresh fluid in behind through vacuum action. Because there is no impeller, diaphragm, or set of check valves in contact with the process fluid, the Rapide pump can run dry indefinitely without damage and can be reversed instantly to clear or reverse-prime a line, a capability that mechanical seal-based pumps simply cannot offer. Standard hose speeds on the Rapide range are typically 68, 137, or 196 rpm, allowing the same head to be matched to different flow duties by changing pulley ratio rather than the pump itself.
This sealed, single-moving-part architecture has direct practical benefits on site: there is no mechanical seal to leak or replace, no valve to clog with solids, and no risk of product contamination since the hose is the only wetted component. Abrasive slurries, high-viscosity fluids, and shear-sensitive chemicals can all be handled by the same Verderflex Rapide pump body simply by selecting the appropriate hose compound, and because there is no dynamic seal under pressure, the pump maintains rated performance even as upstream or downstream pressure conditions fluctuate.
Engineering Design of the Verderflex Rapide
The Verderflex Rapide pump is built around a rugged cast aluminium pump head and housing designed for rugged industrial environments, paired with an IP55-rated single- or three-phase gearmotor sized to the selected hose bore and speed. The rotor assembly uses shoes or rollers running in a lubricated track to compress the hose evenly across its full working stroke, minimizing localized wear and extending hose service life compared to lower-cost tube pump designs. A hinged or bolt-on cover plate gives direct access to the hose element, and Verder’s tool-minimal design allows a full hose change to be completed in a matter of minutes rather than the extended downtime typical of reassembling a mechanical seal or diaphragm pump.
Installation is straightforward: the Rapide pump can be mounted as a standalone skid-fed unit or integrated directly into an OEM system such as a packaged dosing skid or process line, with flanged or threaded connections sized to match the selected hose bore. Because the motor, gearbox, and pump head form a single compact assembly, the Rapide footprint is significantly smaller than an equivalent-duty diaphragm metering pump package, and the absence of a separate seal flush or barrier fluid system removes an entire subsystem from the installation drawing. Standard hose materials include Verderprene and silicone, both rated for FDA and USP compliance where hygienic transfer is required.
Key Features
The Verderflex Rapide pump concentrates decades of Verder hose-pump engineering into a compact, field-serviceable package. Its standout capabilities include:
- Seal-less, valve-less peristaltic design that eliminates the leak paths and maintenance points found in centrifugal and diaphragm pumps.
- Flow rates to approximately 1.67 GPM and discharge pressure to 2 bar (29 PSI), suitable for metering, transfer, and dosing duties alike.
- Heavy-duty cast aluminium housing with an IP55-rated gearmotor built for continuous industrial and outdoor service.
- Tool-minimal hose change that restores full pump performance in minutes, dramatically reducing unplanned downtime.
- Dry-run capability and instant reversibility for line clearing, re-priming, and abrasive-slurry handling without damage.
- Standard hose bores up to 12 mm (0.5 in) with FDA and USP-compliant Verderprene and silicone hose options.
- Operating temperature rating to 85°C (185°F), supporting hot process fluids and elevated ambient conditions typical of Gulf industrial sites.
- Selectable standard speeds of 68, 137, and 196 rpm, allowing flow tuning without changing the base pump.
Industrial Applications
The Verderflex Rapide pump is specified wherever abrasive, viscous, or chemically aggressive fluids must be metered or transferred without risk of seal failure, including polymer and coagulant dosing at water and wastewater treatment plants, acid and caustic transfer in chemical processing, slurry handling in mining and mineral processing, and general effluent and sludge transfer in industrial plants. Its dry-run tolerance and rapid hose-change design also make it a preferred choice for batch dosing skids and mobile transfer units used on temporary sites across the region.
As the officially authorized partner for Verder, Seven Star LLC distributes and supports the Verderflex Rapide pump across municipal and industrial water treatment plants, RO desalination chemical dosing systems, district cooling water treatment loops, and process plants operating within the Sohar and Salalah economic zones. Our regional hose and tube inventory, held locally in Oman, allows plant maintenance teams across the GCC to keep the Rapide pump running with minimal downtime instead of waiting on overseas shipment of wear parts.
