Construction pump
The Yamaha YP40T construction pump uses a 357cc, OHV 4-stroke engine that is quieter, more powerful, and consumes less fuel than comparable engines, Yamaha sources report.
It can pump up to 449 gpm (26,940 gph) through a four-inch port. The unit is built for dewatering applications such as job site excavations, utility vaults, motocross tracks, mining sites, lakes and ponds, and barge holds.
The unit produces an 89-foot total head, with a 26-foot suction head and can handle solids up to 1-1/16" The impeller and volute case are cast iron for greater strength and durability; and they withstand wear from grit, sand, silt and other abrasive materials. Cast iron cylinder lining has optimal heat dissipation and the automatic oil warning system shuts off engine before oil level is low that prevents engine damage, avoids costly repairs, minimizes down time and enhances long term durability.
The new-style silicone carbide (SIC) seal has better durability compared to conventional carbon ceramic seals. Its 4-inch Standard National Pipe Thread (NPT) fittings connect easily to standard suction and discharge hoses. The model has a three-year industrial and residential warranty with optional Yamaha Extended Service (Y.E.S.) for customer peace of mind
The Transistor Controlled Ignition (T.C.I.) produces a clean, efficient spark that assures fast, easy starting. low maintenance and reliable operation, The auto decompression automatically “opens” exhaust valve to reduce compression for easier starting. The YP40T meets the strictest environmental standards - EPA and CARB, Yamaha sources report.
