SERIES ‘E’ VERTICAL PUMPS

Specifications

The rugged Series ‘E’ sump pump is a tough, all machined pump designed for years of trouble-free operation. This pump features a cantilevered, sleeved SS shaft which eliminates bearings and seals, resulting in a pump that can run dry without damage. A vapor seal between the rotating shaft and the support column protects the motor. The compound impeller prevents liquid from rising in the column, even at maximum TDH, while the semi-enclosed bottom impeller provides efficient flow performance at low horsepower. A unique characteristic of the Series ‘E’ pump is its ability to perform on continuous duty as a level control when an optional suction extension pipe is installed. With the motor energized, the pump will self-prime when liquid is above impeller level. The solution level will then be pumped down to the end of the suction extension, the pump will lose prime, then reprime when liquid again reaches the impeller. Discharge pipe assembly, suction extension and suction strainer are available options.

Features:

• Flows to 20 gpm or 15ft. TDH @ 60 Hz
• Non-metallic solution contact CPVC, PP, PVDF
• Dry operation will not damage pump

SERIES ‘ESS’ & ‘ECI’ METAL VERTICAL PUMPS

Specifications

The Series ‘ESS’ and ‘ECI’ vertical pumps feature a high efficiency semi-open impeller, cast construction for superior strength and corrosion resistance, and a cantilevered SS 316 shaft guided by a graphite or Rulon bushing. This same bushing design and unique column assembly allows for reliable operation with columns up to 44″. The bushing is lubricated by the product being pumped, thus no external flushing liquid is required. However, since the bushing is being product flushed, these pumps must be used inside the tank. The optional heavy duty mounting plate uses a clamp arrangement which allows it to be positioned anywhere along the length of the pump column. The optional discharge pipe then fits through the mounting plate for easy drop-in installation. Pumps are constructed of SS 316 throughout for maximum corrosion resistance. Gasket is a synthetic fiber with cast iron, PTFE with 316 SS, shaft vapor seal is FKM. Shaft is available in four lengths to 44″. Graphite or Rulon shaft bushing provides vibration-free service and is located directly above the semi-enclosed high efficiency impeller, therefore, it is product flushed. Optional mounting plate can be clamped and tightened at any given point on the pump column, which allows the pump to be set at the desired depth. Motors are 3450 RPM @ 60 Hz or 2850 @ 50 Hz, TEFC or EXP, painted with two-part epoxy paint. Single phase TEFC motors include 8 ft. (2.4m) line cord.

Features:

• Flows to 180 gpm or 90 ft. TDH @ 60 Hz
• Available in13″, 20″, 32″ and 44″
• Available in two sizes – 1 1/4″ x 1″ and 2″ x 1 1/2″ NPT
• Motors are standard NEMA ‘C’ face (.75 – 5.0 HP)
