5 performance ranges with improved hydraulics - 18, 25, 30, 45, 60 & 70 lpm Stainless steel and thermoplastic bracket and discharge head configurations SandHandler top bearing system 7/16” stainless steel hex shaft Internal Flomatic ® check valve with removable retainer 4400 Tri-Seal 50Hz
New, full-floating stage design allows each impeller to move independently for improved performance & abrasive handling Diffuser – Noryl ®, with floating stainless steel hub seal Disc – Noryl ®, with stainless steel impeller eye seal Impeller - Celcon ®, high efficiency Phenolic/graphite washer - further reduces recirculation & provides increased down-thrust protection 4400 Tri-Seal 50 Hz
Impeller High efficiency design – scalloped vane profile Celcon material works with integrated 300 series eye surface. Excellent in abrasives. Fluted hub design is engineered to provide a water barrier between the top of the impeller and the floating hub seal.
RTD Design Impellers Combines radial and turbine impeller designs Impeller vane cavity expands in height and width Higher efficiency Patent pending design
Top Bearing Hex Design – proprietary material mix Withstands wear in abrasives conditions Positive locked position Ceramic bearing sleeve harder than sand. Allows for years of service The two shapes work together as an assembly Self-flushing – allows sand to easily pass through the bearing area – not trapped
