The Flowserve ECPJ is a rugged, single-stage vertical lineshaft sump pump designed to perform tough jobs reliably, under a variety of difficult conditions. Based on a modular design system, the ECPJ pump provides dependable performance while offering maximum mechanical and hydraulic design flexibility. Fully compliant with ISO 13709/API 610 (VS4), latest edition, each ECPJ pump can be custom engineered for the specific application in which it will be used.A range of impeller and casing designs allows the pump’s hydraulic characteristics to be tailored to service requirements.
Pump Casing and Cover features
Dynamically Balanced Precision Cast Impeller limits vibration and ensures smooth operation over a wide flow range. An anti-rotation impeller nut positively locks the impeller to the shaft without exposing its threads to the pumped fluid.
ISO 21049/API 682 Seal Chambers allow for installation of cartridge style single and dual pressurized mechanical seals to meet required safety and environmental requirements.
