Product Overview
The Lowara 1HM20N11T is a precision-engineered pump. Continuous fluid distribution within commercial HVAC environments requires consistent pipeline pressure. Technicians deploy this horizontal centrifugal pump across industrial utility networks to maintain stable liquid transfer capabilities.
System capabilities achieve a Max Head 119 m and produce a Max Flow 40 L/Min. The drive unit requires 1.1 kW of electrical power running exclusively on a 415v circuit. Pipe connections are sized at exactly 25 mm for the suction and discharge lines.
Internal fluid routing depends on a highly efficient multistage configuration that decreases structural vibration. The precisely aligned impellers generate constant flow behaviour, optimizing mechanical energy transfer throughout the fluid delivery process.
The fully metallic AISI 316L stainless steel construction protects vital internal components from mechanical wear. External defense is achieved through an air-cooled motor enclosure carrying an IP 55 rating, alongside a precise mechanical seal preventing leakage.
FEATURES- Wetted parts forged entirely from AISI 316L stainless steel
- Close-coupled horizontal mounting configuration
- Continuous duty short-circuit electric motor
- WRAS and ACS approved for human consumption water
- Handles varied fluid temperatures up to +120°C
- Reduced leakage risk through specialized sealing
- IP 55 rated exterior physical housing protection

Under elevated fluid temperatures, what operating pressure limit and temperature range are sustained?
Thermal operating limits on the 1HM20N11T permit liquid temperatures from -30°C to +120°C backed by a maximum working pressure rating of 16 bar (PN 16).
How efficiently does this multistage pump lift water upward across vertical installations?
Fluid elevation pressure generated by the 1HM-20N-11T reaches a peak dynamic head of approximately 119 m.
What maximum water flow rate and plumbing connection diameter does this booster maintain?
Water circulation piping receives a maximum delivery flow volume of approximately 40 L/Min from the 1HM 20N 11T via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How does the stainless alloy casing and seal assembly safeguard this booster from corrosion?
Robust metallurgy in the 1HM_20N_11T features AISI 316L stainless steel pump casing, diffusers, and closed impellers, protected by precision seals against corrosion.
What electrical motor kilowatt rating and operating supply voltage are engineered for this booster?
The motor driving the 1HM20N11T provides a rating of 1.1 kW (1.5 HP) powered by 380–415 V, 50 Hz, three-phase drawing 3.85 / 2.22 A.
