Product Overview
The Lowara 3HM07S07T provides efficient and reliable pumping performance. Fluid dynamics within modern industrial environments demand consistency, a requirement addressed by the e-HM series. This unit bridges the gap between high-pressure performance and efficient energy usage, maintaining steady output throughout extended duty cycles. Operators requiring reliable pressure circulation for closed-loop cooling or process supply will find this horizontal configuration integrates smoothly into existing infrastructure, providing stable flow characteristics even when dealing with varied suction conditions.
Operational threshold limits are defined by a Max Head 52.3 m alongside a Max Flow 73.3 L/Min. Powering this hydraulic sequence is a 0.75 kW / 415v motor, ensuring the assembly remains within specified electrical parameters while maintaining throughput. The internal hydraulic geometry is calibrated to support these metrics, allowing for consistent liquid transfer across residential or light industrial applications without degradation in output consistency.
Mechanical movement is governed by a series of AISI 304 stainless steel stages that maximize hydraulic efficiency. The multistage arrangement balances internal liquid friction against kinetic energy transfer, enabling the pump to reach target heads while minimizing noise levels to 55 dB. This configuration relies on a precisely aligned rotating assembly to ensure that suction and delivery remain continuous, preventing cavitation risks even at higher rotational velocities.
Housing consists of a robust AISI 304 stainless steel body, supported by an IE3 efficiency motor rated to IP55 standards for protection against dust and low-pressure water jets. Installation requires simple 25mm suction and delivery connections, permitting rapid deployment into standard piping layouts. The assembly utilizes an advanced mechanical seal interface to ensure long-term integrity, while the short-circuit squirrel-cage motor ensures rapid acceleration from start-up.
Features:
- Integrated 2-pole asynchronous squirrel-cage motor technology
- Class 155 insulation for high thermal environment stability
- AISI 304 casing designed for 16 bar maximum operating pressure
- Compatible with IE3 efficiency standard motor architecture
- Threaded Rp connection points for standard plumbing integration
- Operational liquid temperature handling from -10°C to +120°C

What maximum delivery flow rate does this multistage circulation pump discharge across piping?
Connecting through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, the 3HM07S07T maintains a maximum delivery flow volume of approximately 73.3 L/Min across plumbing lines.
Which stainless alloy components safeguard the impellers and casing against particulate erosion?
Preventing fluid corrosion, the 3HM-07S-07T features an AISI 304 stainless steel body, closed stainless impellers, and chemical attack resistant seals.
What supply voltage and motor power rating in kilowatt are required for this multistage unit?
Electrical motor power on the 3HM 07S 07T reaches 0.75 kW (1.0 HP), powered by a 380–415 V, 50 Hz, three-phase electrical feed drawing an electrical current of 1.53 A.
How is reverse flow prevented when installing this circulation pump in a horizontal position?
Installing an external in-line check valve downstream of the 3HM_07S_07T stops reverse flow, while the pump rests on a horizontal base with drainage.
What peak vertical push head can this circulation multistage pump achieve upward?
Vertical pressure development enables the 3HM07S07T to reach a peak dynamic elevation head of approximately 53.1 m.
