Item # 4VX20M6-53, Explosion-proof 4" Non-Clog Wastewater Pumps
|
|
|
|
|
|
Capacity : 715 gpm (45.1 lps)
Head : 59 ft (17.9 m)
Standard (4V) and Explosion-Proof (4VX) Construction
The 4V and 4VX (Explosion-proof) Submersible Wastewater Pumps pass a full 3" spherical solid and are the ideal choice when selecting a pump for your next application. Myers rounded port, 2-vane, enclosed impellers prevent solids from binding or clogging and offer high operating efficiencies to cut your pumping costs. The 4V series modified constant velocity volute case provides smooth operation over an extended portion of the performance curve for longer seal and bearing life. For use in municipal lift stations, treatment plants and industrial waste applications. Myers offers a complete line of wastewater pumps, lift-out rail assemblies, controls and accessories to meet your needs.
Advantages By Design
High efficiency hydraulic design cuts pumping costs and extends life of fluid end components.
- Two-vane, rounded port, enclosed type impellers handle 3" solids with ease at high operating efficiencies.
- Modified constant velocity volute offers quiet operation, low radial loads over extended portion of performance curve.
Durable motor will deliver many years of reliable service.
- Oil-filled motor for maximum heat dissipation and constant bearing lubrication.
- Heat sensor thermostats imbedded in windings protect motor from overheat conditions.
- Seal leak probe in seal chamber warns of moisture entry; helps prevent costly motor burnout.
- Double tandem shaft seals prevent sewage from entering motor.
- Power and control cables are double sealed with epoxy and compression grommet.
Available with optional UL approval for use in class 1, Group D hazardous locations (4VX only).
