Product Description

The Dayliff DDP 50A is a self‑priming automatic pressure‑controlled peripheral booster pump designed for domestic and small‑scale water supply where on‑demand pressure is needed. It features an integrated diaphragm‑type pressure vessel and pressure switch which automatically starts the pump when system pressure drops (for example when a tap opens) and stops it when the required pressure is reached, delivering consistent water pressure without manual switching. The pump’s robust construction makes it suitable for homes, small buildings, showers and other pressurized water systems.

Key Benefits and Features

• Automatic pressure‑controlled operation with self‑priming capability, eliminating the need for manual priming in most setups.
• Diaphragm‑type pressure vessel and mechanical pressure switch provide reliable start/stop control based on water demand.
• Durable cast iron pump body with brass impeller and wearing surface inserts for long service life.
• Close‑coupled single‑phase motor with thermal overload protection ensures safe, continuous operation.
• Self‑priming design allows the pump to lift water from shallow sources without additional priming devices.
• Compact and quiet performance ideal for domestic water boosting, shower pressure enhancement and small irrigation needs.
