Product Overview
The Lowara 3HM11N09M is a precision-engineered pump. Fluid movement across demanding industrial cooling circuits requires consistent pressure output and material resilience. This horizontal multistage assembly integrates seamlessly into small-to-medium process loops where chemical compatibility is vital. Suction and delivery are handled via standard 25mm threaded connections, facilitating integration into existing piping grids without adapters.
Operational parameters are defined by a Max Head 77.5 m alongside a Max Flow 73.3 L/Min. The drive system utilizes a single-phase 0.95 kW motor, providing the necessary torque for continuous duty cycles. Efficiency and performance metrics remain stable across varying load conditions, meeting rigorous process requirements.
Advanced hydraulic performance is governed by a series of closed-type AISI 316L stainless steel components. These elements are configured to minimize flow turbulence and optimize energy conversion during high-head operations. The internal architecture maintains tight tolerances, ensuring smooth fluid transit from the inlet through the final discharge stage.
Housing construction centers on an AISI 316 stainless steel casing, selected for its resistance to corrosive agents. The TEFC motor is housed within an IP55 rated enclosure, ensuring protection against moisture and airborne particles during operation. Thermal stability is maintained within a liquid range of -10°C to +60°C, supported by an insulation class 155 (F) motor configuration.
Features:
- Integrated 2-pole surface motor operating at approximately 2900 rpm
- Fitted with silicon carbide/carbon mechanical seal interfaces
- Compliant with ISO 9906:2012 Grade 3B hydraulic standards
- Optimized for clean liquid transfer within industrial supply environments
- Short-circuit squirrel-cage motor configuration for stable torque delivery
- Includes EPDM elastomer sealing components for chemical compatibility

How are internal fluid pathways protected against corrosion through metallurgy and seal materials?
The metallurgy framework of the 3HM11N09M utilizes AISI 316L stainless steel pump casing, diffusers, and closed impellers, complemented by precision seals against corrosion.
In professional electrical circuits, what supply voltage and motor power kilowatt rating are needed?
Running via 220–240 V, 50 Hz, single-phase, the 3HM-11N-09M requires a 0.95 kW (1.3 HP) motor pulling a full load current of 5.45 A.
For high-pressure water transfer, what operating pressure boundaries and temperature limits apply?
Thermal and hydraulic limits on the 3HM 11N 09M ensure a maximum working pressure rating of 16 bar (PN 16) with fluid temperatures from -10°C to +60°C.
When elevating water through facility risers, what peak dynamic head does this pump sustain?
Producing steady elevation lift, the 3HM_11N_09M delivers a peak dynamic head capability of approximately 77.5 m.
In commercial water loops, what maximum flow capacity and outlet port dimensions are built in?
Water supply pipework connects to the 3HM11N09M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, which discharges a maximum delivery flow of approximately 73.3 L/Min.
