8QP77 Series

  • Deehp’s heavy-duty 8-inch cast stainless steel fountain pump is purpose-built for harsh natural water conditions containing suspended sediment and fine debris. Adopting thick, robust cast SS304 impellers and diffusers, it delivers superior wear resistance and anti-clog performance compared with conventional stamped SP-series pumps. Its heavy-duty cast structure withstands long-term abrasion caused by water impurities in lakes and rivers. Exclusively matched with 40kW–75kW 8-inch heavy-duty water-cooled submersible motors, it supports 24-hour non-stop full-load operation. With an adjustable head range from 20m to 332m, it ensures stable, long-lasting fountain effects for large-scale municipal lake and river landscape projects.

Overview

  • Deehp’s 8QP77 sub-series is a cast stainless steel submersible fountain pump with a uniform 8-inch outer barrel diameter, fixed rated flow of 77 m³/h, standard 50Hz power frequency and rated rotating speed of 2850rpm. All pump units within this Deehp sub-series share identical casing size, design flow, frequency and rotational speed; performance differences only come from varying impeller stage counts and matched Deehp motor power to meet diverse fountain lift requirements.
