Product Overview
The Lowara 3HM13S11M serves as a precision-engineered solution for liquid transfer and pressure regulation in diverse professional environments. By integrating a multistage hydraulic arrangement, this unit excels at moving clean water through secondary loops, cooling circuits, or pressurization systems where consistent, stable flow dynamics are required. Its compact horizontal orientation facilitates integration into constrained plant room layouts or skid-mounted water management assemblies, ensuring straightforward piping alignment.
Hydraulic output is managed by an efficient motor providing a maximum power rating of 1.1 kW / 240v. The pump architecture supports a performance capacity reaching a Max Head 93.1 m and a Max Flow 73.3 L/Min. Engineered for clean water, the unit features 25 mm inlet and outlet porting, maintaining the strict hydraulic integrity essential for high-pressure irrigation or process water tasks. The technical design ensures the motor remains operational under continuous loads while meeting stringent efficiency standards.
Construction priority is placed on structural longevity and fluid-path purity. The pump utilizes an AISI 304 stainless steel hydraulic assembly, providing a corrosion-resistant environment for the internal liquid flow. The staging configuration minimizes turbulence while maximizing the energy transfer efficiency inherent to the e-HM series design. This configuration allows for smooth pressure transition across each stage, effectively dampening vibrational stress during high-head operation while ensuring long-term seal stability.
Designed for demanding service, the unit incorporates an IP55 rated motor with a TEFC enclosure to protect internal electrical components against ingress in humid or industrial settings. The structural design employs a robust stainless steel body connected directly to the motor flange, minimizing potential leak paths associated with traditional pump architectures. Maintenance access is simplified through a modular design that facilitates straightforward seal inspection and routine service procedures as required by industrial duty cycles.
Features:
- TEFC squirrel-cage motor configuration for thermal management
- AISI 304 stainless steel wetted hydraulic components
- IP55 rated motor ingress protection for stationary use
- Dual O-ring casing sealing arrangement for pressure containment
- ISO 1680 standard compliant acoustic vibration control
- Premium efficiency IE3 electrical motor winding technology

What electrical power in kilowatt and operating current feed this single-phase transfer pump?
Powered by a 220–240 V, 50 Hz, single-phase electrical feed, the 3HM13S11M delivers a motor power rating of 1.1 kW (1.5 HP) at an electrical current draw of 6.41 A.
What horizontal mounting guidelines and non-return check valve piping apply to this supply booster?
Backflow prevention across horizontal pipe runs requires installing an external non-return check valve immediately downstream of the 3HM-13S-11M, which must rest on a horizontal base with drainage.
What maximum dynamic head is produced by this high-pressure multistage booster?
Vertical lift pressure is developed by the 3HM 13S 11M, which maintains a peak dynamic head capability of approximately 96.4 m across its stages.
What peak fluid flow rate can this stainless transfer pump deliver through its discharge port?
Plumbing connection lines interface with the 3HM_13S_11M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 73.3 L/Min.
How does the stainless construction defend this multistage supply pump against chemical attack?
Corrosion defense across the 3HM13S11M relies on high-grade AISI 304 stainless steel casing alloys and closed stainless impellers with EPDM elastomers to protect against chemical attack.
