🔧 ESPA ES4 4" Submersible Hydraulic Section: pump body to fit to a 4" motor
The ESPA ES4 is the hydraulic section of a 4" submersible electric pump, sold without a motor. Fitted to a 4" motor with a NEMA coupling, it is used to pump clean water from boreholes for domestic use, irrigation, agriculture and industry. There are eight series (ES4 01 to ES4 16), each with several sizes; the tables show the dimensions and head values for each flow rate.
✔ ES4 Hydraulic Features
- ✔ Body, suction, discharge and shaft: AISI 304 stainless steel
- ✔ Diffusers and impellers: floating, made of technopolymer
- ✔ Gaskets: NBR/EPDM
- ✔ Built-in check valve
- ✔ Coupling: NEMA MG1-18.388 standard
