Grundfos Hydro MPC-E Dual CRIE5 Automatic Variable Speed Pressure Boosting Pump Set (Max 330LPM)

The Grundfos Hydro MPC-E Packaged Pump System is a complete pump set with pumps, valves, suction and discharge manifolds, mounted on a common base. The pump system includes a Control panel designed to Grundfos specification. The Pressure booster system is supplied as compact assembly according to DIN standard 1988/T5.

• Hydro MPC-E maintains a constant pressure through continuous adjustment of the speed of the pumps irrespective of the flow rate
• The system performance is adapted to the demand through cutting in/out the required number of pumps and through parallel control of the pumps in operation i.e. cascade.
• Pump changeover is automatic and depends on load, time and fault.

The Grundfos Hydro MPC-E boosting Package is comprised of the following components:

• Pump - Parts in contact with the pumped liquid are manufactured in stainless steel EN DIN 1.4301.
• Pump bases and heads are stainless steel (CRI). The pumps are equipped with a service-friendly cartridge shaft seal, HQQE (Silicon Carbide/Silicon Carbide/ EPDM). Pumps are fitted motors, the Grundfos MGE IE5 premium efficiency permanent magnet motors to 11kw and High efficiency IE3 MGE motors 15-22 kW.
• Manifolds - Two manifolds of stainless steel EN DIN 1.4301 and incorporate loose-ring, epoxy coated, aluminium inlet/outlet flanges to DIN dimension.
• Modular base frame - Pumps are mounted to a common base frame (5 and six pump packages may be split) manufactured in either folded and welded stainless steel or hot dip galvanized fabricated mild steel (system size dependant).
• One non-return valve (POM) and two isolating valves for each pump.
• Dry-running protection and diaphragm tank are available according to the list of accessories. Pump operation is controlled by Control MPC with the following functions:

• Intelligent multi-pump controller, CU 352.
• Constant pressure control through continuously variable adjustment of the speed of each individual pump.
• PID controller with adjustable PI parameters (Kp + Ti).
• Constant pressure at setpoint, independent of inlet pressure.
• On/off operation at low flow.
• Automatic cascade control of pumps for optimum efficiency.
• Selection of min. time between start/stop, automatic pump changeover and pump priority.
• Automatic pump test function to prevent idle pumps from seizing up.
• Possibility of standby pump allocation.
• Possibility of backup sensor (redundant primary sensor).
• Manual operation.
• Display of individual pump run hours
• Soft pressure build-up
• Internal time clock based operation
• Possibility of external setpoint influence
• Log function
• Setpoint Ramp
• Possibility of digital remote-control functions:
• System on/off,
• Max., min. or user-defined duty
• Up to 6 alternative setpoints.
• Digital inputs and outputs can be configured individually.
• Pump and system monitoring functions:
• Minimum and maximum limits of current value
• Inlet pressure
• Motor protection.
• Sensors and cables monitored against malfunction.
• Alarm log with the previous 24 warnings/alarms, time & date stamped.
• Display and indication functions:
• Colour Screen display
• Green indicator light for operating indications and red indicator light for fault indications
• Potential-free changeover contacts for operation and fault.
• Grundfos Bus communication options via Grundfos CIM.
• Optional Grundfos Remote Management (GRM)
• Booster system includes panel door mounted system emergency stop button and the additional IP602 panel that includes the following features:
• Easy navigation via intuitive push buttons
• Individual pump run & fault LED’s
• System alarm LED
• Multifunction pump liquid temperature display
• Input facility to connect optional pump liquid temperature sensors
• Pump liquid temperature protection, if optional sensors connected
• Phase failure indication when optional phase failure protection is included
• Alarm reset/mute of audible alarm button
