The rear part of the pressure body (discharge part) of the Astral Sena pump for flows of 4–7 m³/h and a 230 V supply is a structural part that closes off the hydraulic section of the pump from the motor drive. Its damage or leakage manifests itself as water leaking from the pump or a drop in discharge pressure.
The original replacement part is made of durable plastic with precise dimensions ensuring correct seating on the seal and a flawless connection with the other pump parts. The dimensional compatibility eliminates the risk of vibration or leakage after installation.
Replacing this part is an economically efficient service repair that extends the pump’s service life by many years. We recommend performing the replacement according to the manufacturer’s instructions using a new seal to ensure watertightness.
