Product Overview
Engineered for versatility in building services and industrial liquid management, the Lowara 5HM11S15M serves as a reliable horizontal multistage centrifugal solution. This pump is specifically configured to manage clean water transfer where flow stability and pressure consistency are essential. Its architectural design allows for seamless integration into diverse hydraulic networks, offering a direct response to the requirements of modern irrigation systems and residential supply lines where effective movement of clean fluids is mandatory.
The pump exhibits significant hydraulic capability, reaching a Max Head 78.2 m and a Max Flow 142 L/Min. Powering this unit is an IE3 efficient motor, utilizing a 1.5 kW draw at 240v. The mechanical assembly utilizes a 32 mm inlet and a 25 mm outlet to accommodate standard plumbing configurations. Thermal performance is managed within an operating envelope suitable for liquids ranging from -10°C to +60°C, ensuring that the assembly maintains its operational integrity across varied ambient environmental conditions.
Fluid dynamics are optimized through the use of AISI 304 stainless steel impellers, which minimize cavitation potential while maximizing energetic efficiency. The multistage arrangement effectively stacks hydraulic pressure, providing a steady output even under fluctuating demand. This series prioritizes laminar flow characteristics, reducing internal friction losses and providing consistent delivery across the entire performance curve, supporting long-term reliability in continuous duty cycles.
Designed with a TIG-welded external sleeve and a robust bracket for structural rigidity, the unit employs a dual O-ring seal system to minimize maintenance intervention points. The TEFC motor is shielded under an IPX5 rating, providing protection against fluid ingress, while the insulation class 155 (F) handles thermal fluctuations during startup and high-load operation. The connection ports use standard Rp threading for straightforward field piping, and the overall construction leverages high-grade stainless steel to ensure longevity in fluid contact areas.
Features:
- WRAS and ACS certification for safe drinking water circulation
- TEFC motor enclosure with IP55 rating for environmental shielding
- Standardized Rp threaded connections for simplified pipe integration
- AISI 304 stainless steel liquid-contact components for corrosion resistance
- Thermal management optimized for continuous operation cycles
- Integrated 2-pole squirrel cage rotor geometry for precise speed stability

What kilowatt rating and electrical supply voltage run this single-phase circulation motor?
Powered by a 220–240 V, 50 Hz, single-phase electrical feed, the 5HM11S15M delivers a motor power rating of 1.5 kW (2.0 HP) at an electrical current draw of 8.42 A.
How does an external check valve prevent reverse flow across this horizontal circulation booster?
Backflow prevention across horizontal pipe runs requires installing an external non-return check valve immediately downstream of the 5HM-11S-15M, which must rest on a horizontal base with drainage.
What maximum vertical head and fluid lift elevation does this cooling pump provide?
Vertical lift pressure is developed by the 5HM 11S 15M, which maintains a peak dynamic head of approximately 82.0 m across its stages.
What maximum delivery flow rate does this multistage cooling pump discharge across piping?
Plumbing connection lines interface with the 5HM_11S_15M via Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 142 L/Min.
Which construction materials safeguard the hydraulic stages of this pump against particulate wear?
Corrosion defense across the 5HM11S15M relies on high-grade AISI 304 stainless steel casing alloys and closed stainless impellers with EPDM elastomers to protect against chemical attack.
