Single-Phase Rain Barrel Pump 40 m 40 l/min for Home & Garden — Pentax PM45A
ADVANCED SELF-PRIMING CONVENIENCE: Features specialized built-in self-priming capability (unique to the 45 A series), allowing fast, automatic water drawing without losing prime, even when air or gas bubbles are present in the suction line.
HIGH-EFFICIENCY HYDRAULIC POWER: Engineered with an advanced peripheral vortex mechanism that generates 3 to 7 times greater pressure than standard pumps of similar size. Delivers a maximum head of up to 40 meters (6 Bar max pressure) for quick and powerful water delivery.
ULTRA-LOW ENERGY CONSUMPTION: Powered by an optimized 0.37 kW (0.5 HP) single-phase 230V motor (2.3A rated current). Designed to maximize water movement while keeping electricity consumption minimal, reducing your energy bills and overall operational costs.
VERSATILE HOME & GARDEN USE: Perfect for automatic household water distribution, low-pressure hydrofoil tanks, garden and orchard irrigation, and drawing clean water from storage tanks or reservoirs.
HEAVY-DUTY ITALIAN QUALITY & LOW MAINTENANCE: Crafted in Italy by PENTAX Industries S.p.A. using a durable cast iron pump body, corrosion-resistant brass impeller, ceramic-graphite mechanical seal, and stainless steel AISI 416 shaft. Features a simplified single-control-valve layout for lower repair and maintenance costs (IP44, Class F insulation).
RAIN BARREL PUMP: Looking for the best pump for rain barrel watering? The Pentax PM45A Single-Phase is a peripheral rain barrel pump for pumping water from rain barrels, water butts and small tanks, transferring clean water for garden watering, plants and outdoor use.
