Double mechanical seals made of silicon carbide and pressure-bleed design. Stator windings can be replaced without removing stator from frame. Special steel is used or the impeller, ceramic are used for the liner ring, and the casing, suction cover and intermediate casing are of special molded rubber (in certain pump types). Result: excellent resistance to water. The pump base is of special design, thus resistant to shock. Cooling of entire outer surface of motor by flowing water keeps motor uniformly cooled and improves durability. Unique design of impeller nut prevents air lock during unsteady operation. Motor protection prevents damage of motor due to overload, or open phase.

45 ENZ2 HEAVY DUTY SUBMERSIBLE SAND PUMPS APPLICATIONS Drainage in raw concrete plants Drainage in quarries Drainage in grinding plants Drainage at civil engineering sites Water intake from rivers Drainage in areas with sand sedimentation Drainage in sand utilization plants FEATURES Load limiting characteristics prevent overload if cover current occurs. If optional water jacket is fitted, motor can operate exposed to the air. Vortex type mixing blade provides outstanding mixing performance. Mixing blade, suction cover and impeller are made of high chrome cast iron, which has excellent resistance to pumping liquid. Pump and motor can be disassembled separately, facilitating disassembly and inspection work. A balance hole is used for pressure bleed of the mechanical seal. Combined with the liner ring (of special rubber), this makes it difficult for slurry to enter the seal, which greatly improves durability. Both the upper and lower parts of the mechanical seal are made of silicon carbide, which are durable. Quick discharge connector can be provided. Mixing nozzle, permitting mixing and pumping of sediment water, can be provided as an option. When a special strainer (optional) is fitted, water containing accumulated mud and sand deposits can be force-drained.

48 EB HYBRID SUBMERSIBLE PUMPS APPLICATIONS Rainwater and spring water drainage Drainage of water at bottom of pools and tank Fountains Water intake from rivers FEATURES Employment of rubber casing makes pump lighter and stronger. Compact, portable pumps can be used for a wide variety of applications. Original vortex design eliminates locking due to sand or mud. Pumped liquid flows round and cools all the outer surface of the motor, making motor compact and sturdy. Capacitors, cables and others parts likely to need maintenance are grouped at the top of the pump, and can be accessed simply by removing the cover.
