Product Overview
The Lowara 3HM11S11T provides efficient and reliable pumping performance. Suction-side fluid handling in high-pressure industrial environments requires the mechanical precision found in this horizontal multistage assembly. By utilizing a compact architecture, the unit manages steady liquid transport for process water applications where space efficiency remains critical. The integration of high-grade materials allows for consistent operation across demanding temperature cycles, ensuring the hydraulics remain stable throughout continuous duty cycles in professional infrastructure.
Operational performance thresholds are defined by a Max Head 82 m alongside a Max Flow 73.3 L/Min. Power input is provided by a 1.1 kW motor designed for 415v supply, ensuring balanced circulation for systems requiring precise flow control. The combination of multi-stage hydraulic design and optimized motor output delivers sustained performance levels for complex fluid loops, maintaining pressure integrity even during peak demand intervals.
Fluid dynamics are governed by a series of stainless steel components engineered to minimize turbulence and maximise hydraulic efficiency. The multistage arrangement enables the pump to reach higher pressures than standard single-stage designs while maintaining a compact footprint. Internal clearances are held to precise tolerances, ensuring that kinetic energy conversion is maximized within the AISI 304 housing structure during continuous operation.
Constructed with a fully AISI 304 stainless steel casing, the unit is protected by an IP55 motor rating. The TEFC, 2-pole squirrel-cage motor ensures thermal management during active cycles, while the 25mm suction and delivery ports provide standard integration into existing supply manifolds. Engineered for resilience, the internal seals are selected for broad chemical compatibility, making this an effective solution for specialized circulation tasks.
Features:
- TEFC 2-pole asynchronous squirrel-cage motor configuration
- IP55 motor protection for environmental resilience
- WRAS and ACS certification for drinking water contact
- TIG-welded external sleeve for structural reinforcement
- ISO 9906:2012 Grade 3B hydraulic compliance standards
- Class 155 (F) insulation for thermal endurance

What maximum vertical elevation head does this commercial multistage unit achieve?
Vertical supply pressure reaches a maximum dynamic head of approximately 83.3 m on the 3HM11S11T.
What peak delivery flow rate can this horizontal multistage unit provide through its outlet?
Water delivery capacity through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge reaches a maximum flow volume of approximately 73.3 L/Min on the 3HM-11S-11T.
How does the stainless casing construction protect this booster from mineral attack and corrosion?
Resisting mineral corrosion and chemical attack, the 3HM 11S 11T employs AISI 304 stainless steel casing alloys and precision closed stainless impellers.
What motor power rating in kilowatt and electrical current draw apply to this circulation booster?
Electrical feed on the 3HM_11S_11T requires a 380–415 V, 50 Hz, three-phase connection, delivering a motor power rating of 1.1 kW (1.5 HP) at an electrical current of 2.21 A.
What horizontal installation positioning and floor drainage clearance apply to this pressure booster?
Anchoring guidelines for the 3HM11S11T call for a level horizontal foundation base with drainage, alongside an external check valve to stop reverse flow.
