ETP Pumps

This is a self-priming pump with 3 m. negative suction. Coupled to 2900 RPM motor. Excellent for handling acidic effluents (not recommended for effluent containing solvents)

A normal centrifugal pump with a priming bowl and a built-in rubber flap valve. Will lift up to 3 mts. depth. Available in completely injection moulded PP. The pump has a Hastelloy Sleeve on the shaft. Very compact and most ideal as it is compatible with heavy vertical submersible pumps. Can be supplied with quick connect coupling for ease of installation on request. No vertical submerged pump can match it for economy and performance. Supplied with Polypropylene Strainer.

How Our Pumps Self-Prime

1. The user must only fill the housing once with the liquid to be pumped or with water. This is designed to retain this priming liquid even if the pump is shut off. When started, the pump impeller mixes air from the suction line with priming liquid. The resulting froth is expelled into the priming chamber where the bubbles collapse, allowing the air to pass off through the discharge. The liquid from the bubbles falls back and is retained in the pump until mixed with more air from the suction line.

2. This process continues until all the air is evacuated from the suction line and the liquid to be pumped rises to the impeller. Normal pumping takes over from here

Parts subjected to wear : Impeller, Shaft Seal Assembly and Volute are replaceable without replacing other pump housings. The built-in check valve ensures retention of the priming liquid and prevents back-flow of the system when the pump is shut off.
