Auto-Priming Diesel Diaphragm Pump for Site Drainage and Solids-Laden Water
The DryMax Diesel Trash Pump is an auto-priming, diesel-fuelled diaphragm pump designed for site drainage where mains power is unavailable. Powered by a Yanmar L48E electric start engine, it handles liquids containing sludge, mud, sewage, sand and suspended spherical solids up to 40mm. No priming equipment or foot valves are required, and the pump can dry-run indefinitely thanks to its nitrile rubber diaphragm design.
What is the DryMax Diesel Trash Pump used for?
• Site drainage and construction dewatering
• In-water works
• Sewage transfer on site
• Hire fleet applications
• Utilities
• Submerged litter and waste removal
Construction and Durability
The pump body is constructed from aluminium, keeping the unit light and strong. The pivoting pump chamber can be operated front-facing or sideways to suit the installation, and allows easy access for maintenance. A 5.4-litre fuel tank provides up to six hours of continuous running. The pump includes a standby engine recoil, BSP male connections and a mud plate. Solids handling up to 40mm in diameter. Suction lift maximum is 8 metres; recommended at 6 metres and below.
Why choose the DryMax Diesel Trash Pump?
The DryMax combines auto-priming capability with indefinite dry-run operation, diesel independence and 40mm solids handling in a site-proven design. The pivoting chamber makes on-site maintenance quick without specialist tools. Available in Drymax 2 (2" inlet/outlet) and Drymax 3 (3" inlet/outlet), with an optional quick-release coupling kit for both models. Each pump is supplied with a two-wheeled site trolley as standard.
