EBARA Submersible Non-clog Pump Model DLFU Model DVFU Model DDLFU water wastewater EBARA International Corporation Standard Pump Division
S ubmersible Non-clog Pump Model DLFU DVFU DDLFU Features Watertight cable entry system prevents capillary action and protects against moisture; reduces maintenance costs Heavy duty, high efficiency, air filled, Class F insulated, rated for F with a. service factor dissipates heat easily; thermal protection in each phase of windings protects; operates cooler with higher efficiencies; longer service life with lower operating costs Self cooling jacket eliminates the need for external pumping devices or special heat transfer fluids; offers simplicity and high reliability by effectively dissipating heat in dry pit applications only Single and double row thrust bearings carries thrust loads with L-0 life of 0,000 hours; ensures long, dependable operation and lowers maintenance costs Mechanically actuated float switch provides early warning of mechanical seal failure; avoids costly motor repairs Double mechanical seals silicon carbide lower seals, carbon/ceramic upper - hard faced upper and lower seals operate in an oil bath; providing longer service life and lower maintenance costs High efficiency impellers pass large solids with high outputs and reduces power consumption; impellers are optimized for hydraulic coverage; lowers operating costs Replaceable wear components maintains working clearances while reducing casing and volute costs
Submersible Non-Clog Pump Model DLFU arrangement options Model DDLFU Dry Pit design Motor cooling is provided by internal recirculation of pumpage through water jacket Mechanical seal oil chamber Model DVFU Vortex design Vortex design is ideal for handling stringy materials without clogging Cable entry system Primary seal grommet (NBR) Secondary sealing O rings (NBR) Epoxy resin prevents capillary action Cable gland (grey cast iron) Solid joint butt connector (copper) Note: Entry system is the same for both power and control cables.
