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.
