Product Overview
Transferring volatile or chemically reactive media through specialized industrial circuits necessitates the resilience of the Lowara 3HM21N22M. This horizontal multistage pump integrates seamlessly into demanding fluid handling environments where traditional materials might fail, offering a reliable path for high-purity process liquid movement. Its architecture is specifically configured to maintain performance in environments ranging from general industrial washing to complex water treatment loops.
Operational parameters for this unit are governed by a Max Head 154 m alongside a Max Flow 73.3 L/Min. Powering these dynamics is a 2.2 kW motor designed for single-phase 220-240V supply. These metrics ensure stable hydraulic delivery across extended plumbing layouts where consistent pressure and flow are required for ongoing, uninterrupted process cycles.
Fluid dynamics are governed by a multistage arrangement utilizing high-grade stainless steel components to prevent cavitation and erosion during operation. The system architecture balances suction performance with high-speed rotation to move fluids effectively across the internal stages without significant energy loss. This configuration ensures that internal hydraulic stability remains intact even when subjected to varying system backpressures in closed-loop configurations.
Housing consists of full AISI 316 stainless steel to ensure longevity when processing aggressive clean liquids. The motor is protected via an IP55 rating, allowing for installation in environments requiring moderate environmental ingress protection. It features a TEFC design for thermal efficiency and operates with a TEFC squirrel-cage configuration, mounted to prevent excessive vibration during heavy-duty task cycles.
Features:
- Internal hydraulic assembly compliant with ISO 9906:2012 grade 3B standards
- Suitable for continuous operational duties in clean liquid handling
- Certified for potable water contact as per international safety standards
- Silicon carbide and carbon resin mechanical seal materials
- Squirrel cage induction motor configuration for TEFC cooling efficiency
- Rp-threaded connection ports compatible with standard stainless plumbing

For dependable hydraulic boosting, what operating pressure rating and liquid thermal limits apply?
Operating reliably within hydraulic limits, the 3HM21N22M accommodates a maximum working pressure capability of 16 bar (PN 16) across -30°C to +120°C.
What maximum upward fluid elevation head can this multistage centrifugal pump attain?
Delivering strong vertical elevation push, the 3HM-21N-22M maintains a maximum dynamic head of approximately 154 m.
When pumping across service lines, what fluid delivery flow rate and port thread are provided?
Peak delivery flow capacity reaches approximately 73.3 L/Min on the 3HM 21N 22M, discharging through robust Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
Under prolonged liquid exposure, what metallurgy and mechanical seal materials protect this booster?
Ensuring complete corrosion defense, the 3HM_21N_22M features alloy AISI 316L stainless steel pump casing, diffusers, and closed impellers and precision mechanical seals.
Under standard facility electrical service, what operating voltage and motor kilowatt rating apply?
The power rating of the 3HM21N22M is established by a 2.2 kW (3.0 HP) motor running on 220–240 V, 50 Hz, single-phase at 10.1 A.
