SEP IV Electric Pump System

Higher flows in ground water recovery.

Application:

Assembly with the electric motor (bottom) and the pump (top). Motor leads are not shown.

Description

The SEP IV Pump System consists of:
• Stainless steel pump
• Electric motor
• Motor lead

The SEP IV is a continuous-duty electric submersible pump designed for the withdrawal of contaminated groundwater or leachate in environmental applications. The pumps require a control mechanism such as the Septek to maintain the desired drawdown level.

Stainless Steel Pump.

The SEP IV pump ends are constructed of 304 stainless steel to provide chemical compatibility for typical environmental installations. Standard pump ends are supplied with durable PBT (polybutylene terephtalate) seals for chemical resistance in most cases. PBT seals are not recommended for use with chlorinated sovants in which case Teflon® seals are recommended. PBT seals generally provide better wear resistance than Teflon®.

The SEP IV pumps are available in eighteen models, producing flow rates up to 75 gpm and to depths up to 400 feet. Other pump ends are available.

Motor. All motors are manufactured by Franklin Electric and are available from 1/2 to 7.5 hp. The motors are available in single phase 230 V, three phase 230 V or three phase 460 V. The three phase motors are used when the pump speed will be variable. Other motors are available upon request.

Motor Lead. Motor leads are supplied separate from the pump end and motor assemblies. DGSI manufactures standard PVC leads in continuous lengths with no splices and individually insulated. The motor lead assembly can be supplied in Tefzel, a material that combines superior mechanical toughness with an outstanding chemical inertness.

Motor leads are 12-gauge wire with either two- or three-wire leads plus the ground. A great variety of choices are offered. Please consult the catalog pages (PDF 800 KB).

Options
