Product Overview
The Lowara 1HM18S11T provides efficient and reliable pumping performance. Corrosive, chemically active municipal supply loops benefit from the resilient construction of this horizontal multistage electric unit. Targeted at industrial cooling systems and demanding process water circuits, the assembly manages high-pressure requirements while maintaining consistent flow dynamics across varied hydraulic environments. Its specific configuration allows for integration into compact skid layouts where space remains at a premium but technical output cannot be compromised.
Operational threshold limits are defined by a Max Head 108 m and Max Flow 40 L/Min. Powered by a 1.1 kW / 415v motor, the unit operates with an IE3 energy efficiency profile to reduce power draw during extended service cycles. These metrics confirm the device is capable of handling significant system resistance while moving liquid volumes that align with precision cooling and secondary process supply demands.
Fluid dynamics are governed by a multistage impeller arrangement crafted entirely from AISI 304 stainless steel. This series of internal components provides a consistent head generation that avoids typical flow fluctuations found in single-stage designs. The internal hydraulic pathway is optimized to minimize friction loss, ensuring that the velocity remains constant throughout the transition from the suction port to the discharge nozzle under varied back-pressure conditions.
Housing consists of a high-grade AISI 304 stainless steel casing, coupled with a TEFC 2-pole motor protected to IP 55 standards. The electrical interface supports 415v three-phase supply, featuring Class 155 insulation to mitigate internal heat build-up. Installation is simplified through standardized 25 mm suction and delivery ports, accommodating standard plumbing layouts without requiring specialized adaptors or structural modifications.
Features:
- Integrated 2-pole squirrel-cage motor with IE3 efficiency classification
- TIG-welded stainless steel hydraulic body for increased pressure containment
- Silicon carbide and EPDM mechanical seal interface components
- Suitable for continuous operation within industrial supply environments
- Compliant with ISO 9906:2012 Grade 3B hydraulic standards
- Operating temperature range capability from -10°C to +120°C

Which stainless materials and closed impellers prevent chemical attack in cooling loops?
Constructed entirely from AISI 304 stainless steel alloy materials, the 1HM18S11T eliminates fluid corrosion and mineral degradation across all stages.
What electrical power rating and three-phase current draw apply to this multistage motor?
Electrical motor power of 1.1 kW (1.5 HP) on the 1HM-18S-11T is driven by a 380–415 V, 50 Hz, three-phase power connection with an electrical current draw of 2.11 A.
Where should this three-phase circulation booster be anchored on a horizontal base with drainage?
Preventing reverse flow across service pipework requires installing an external non-return check valve downstream of the horizontal 1HM 18S 11T on a drained base.
What maximum dynamic head can this stainless multistage booster propel upward?
Multistage vertical push allows the 1HM_18S_11T to maintain a maximum dynamic head of approximately 109 m.
What maximum delivery flow rate does this multistage cooling booster discharge across piping?
Fluid transfer capacity peaks at a delivery flow volume of approximately 40 L/Min on the 1HM18S11T, plumbed via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
