Calpeda 2MXH(L) Horizontal Multi-Stage Pump

The Calpeda 2MXH(L) is a high-efficiency, pre-assembled dual-pump horizontal multistage booster system engineered for constant pressure water supply in residential, commercial, and industrial environments. Designed around Calpeda’s compact and quiet MXHL stainless steel multistage pumps, this system integrates the advanced EASYMAT frequency converter, offering smart pressure regulation, energy savings, and plug-and-play installation.

This twin-pump configuration ensures both performance and redundancy, automatically managing load sharing or alternating duty to extend service life and improve reliability.

EASYMAT is a water-cooled inverter mounted directly on the delivery line of each pump. With just three parameters to configure, setup is fast and intuitive, while real-time monitoring offers insights into system pressure, frequency, and current draw.

SYSTEM INCLUDES

• 2 x Calpeda MXH or MXHL horizontal multistage pumps (in stainless steel)
• Integrated EASYMAT frequency converters (one per pump)
• Stainless steel AISI 304 suction and discharge manifolds
• Ball valves and non-return valves on suction lines
• Ball valves and pressure gauges on discharge lines
• 18L pressure vessel for pressure stabilisation on delivery side
• Compact, pre-plumbed base-mounted booster frame

EASYMAT FEATURES

• Mounted directly on the pump discharge pipe
• Water-cooled for silent, fan-free operation
• Simple startup with 3 programmable parameters:
  • Maximum motor current
  • Operating frequency
  • Desired pressure setpoint
• Digital display for:
  • Current system pressure
  • Motor operating frequency
  • Absorbed current
• Fault codes and alarms

OPERATING MODES

• Constant Pressure Mode: Pump speed automatically adjusts to meet demand, ensuring a stable, pre-set pressure regardless of flow rate changes.
• Fixed Speed Mode: User-defined constant speed operation for simplified control in stable demand environments.

POWER SUPPLY

• Pumps: Three-phase 230V motors
• Input: Single-phase 230V supply (via integrated inverter)

APPLICATIONS

• Multi-residential buildings and complexes
• Commercial water supply systems
• Industrial washdown or process water circuits
• Pressure boosting from rainwater tanks, bore water, or mains
• Agricultural irrigation systems
