75GPD Self-Priming RO Diaphragm Booster Pump (24V DC)

Zero-Inlet Pressure Self-Priming Suction: Engineered with advanced internal check valves delivering a vertical self-suction height of ≥1.5m to 2.0m, allowing RO systems to pull feed water without requiring municipal tap line pressure.

Optimized 72 PSI Working Performance: Delivers a consistent working pressure of 0.5 MPa (72 PSI) and a rated output flow of ≥0.8 L/min (≥800 ml/min), tailored perfectly to drive standard 75GPD RO membranes at peak rejection efficiency.

Low Noise & Low Power Consumption: Utilizes high-purity copper motor windings and rubber shock-absorbing mounting feet, ensuring quiet operation (<50 dB) and low operating current (≤1.0A–1.2A).

High Chemical Resistance & Pressure Relief: Constructed with high-density EPDM/TPU diaphragm materials and a bypass pressure relief range of 0.85–1.05 MPa (123–152 PSI) to protect against hydraulic pressure spikes and prevent leaks.

Complete B2B OEM/ODM Customization: Fully tailorable manufacturing supporting custom capacity tuning (50GPD to 100GPD), voltage variations (24V/36V DC), port connection styles (1/4" female threads or push-in quick connects), terminal wire length, and brand sticker design.
