HT-PRO Stainless steel multi-stage centrifugal pumps
Pump entirely made of stainless steel
Clean water Civil use Agricultural use Industrial use
HT-PRO pumps are designed for high hydraulic performance combined with a
robust, compact and reliable mechanical construction.
PERFORMANCE RANGE
· Flow rate up to 800 l/min (48 m3/h) · Head up to 160 m
INSTALLATION AND USE Designed to transfer clean water free from abrasive
particles and liquids that will not damage the pump’s components. Their high
efficiency and adaptability to a wide variety of applications make them an
ideal choice in the domestic, civil, agricultural, and industrial sectors,
particularly for water distribution along pressure tanks to increase overall
network pressure. Suggested uses include fire-fighting systems, heavy-duty
cleaning applications, industrial power washers, and irrigation.
KEY FEATURES The multi-stage stainless steel construction guarantees
a long service life and a very low noise threshold during operation. Stainless
steel components extend service life and enhance efficiency. Multi-stage
design results in exceptionally quiet operation
