E-S Series

Electric Submersible Pumps

E series and S series models are ideal for installations in small lifting stations where compact size and excellent reliability are required.

Outstanding installation flexibility is ensured by the option of threaded or flanged discharge. These series have hydraulics with grinding system (GRE • GRS), which is recommended for soiled liquids containing fibres and filaments. The high heads (APE • APS) are suitable for use in mainly clean liquids when high pressure level is required.

The GRE and GRS models have an external box with circuit-breaker and current overload protection. This guarantees a reliable operation with soiled liquids (even after idling for a lengthy period), when a high startup torque is required.

Each model undergoes pressurised test to ensure that the motor compartment is airtight and the mechanical seals are fitted correctly, to guarantee excellent reliability.

Details

Stainless steel lifting and carrying handle.

Robust cast iron construction.

GAS threaded and flanged DN32 dischargefor flexible installation.

Stainless steel suction strainer. [APE - APS]

Simple and compact, ideal for installation in small pits, emergency use to empty tank and irrigation.
The option of models with integral float switch makes this range easy and convenient to install.

Single-phase models have internal capacitor. Three-phase models are equipped with thermal protection and relay to safeguard the motor (optional).

Dry motor protection with thermal overload.

One mechanical seal in silicon carbide (SiC) and one lip seal.

Special spiral ribs on the rear of the impeller helps to tear and eject filaments thus prevent over loading of motor.

Single-phase models complete with control box circuit breaker capacitor and overload protection. [GRE - GRS]

Grinding system comprising a three-bladed rotary knife and a plate with holes with sharpened edges that fine-chops filaments, preventing fouling of the impeller.[GRE - GRS]
