Grundfos MTC 10 Water Booster System

The Grundfos MTC 10 water booster system is a compact packaged pressurisation unit combining two parallel multistage centrifugal pumps on a common base with a pre-charged membrane pressure vessel and a GeniVAR II pressure controller, factory-assembled and tested as a complete booster set ready for installation. The MTC 2-40/2-25 variant houses two CM-series horizontal multistage pumps — a 2-40 main pump and a 2-25 standby/duty-assist pump — providing delivered flows up to 4.8 m³/h at outlet pressures up to 6 bar with automatic pump alternation, standby changeover, and overload protection managed by the integrated controller without external PLC intervention. The membrane vessel maintains a minimum system pressure of typically 2.5 bar, preventing pump short-cycling that reduces motor life and increases wear on the system's check valves.

The GeniVAR II controller on the MTC 10 incorporates a constant-pressure PID control algorithm, an automatic self-adjusting setpoint function that tracks system demand without manual recalibration, and an integral duty/standby alternation timer that equalises running hours between the two pumps to extend service life. The controller's self-priming check and dry-run protection cutout are mandatory features under Saudi Civil Defence and NWC regulations for water supply systems in commercial and residential buildings, as both pump protection and occupant safety requirements. The MTC 10's IP44 electrical enclosure rating provides adequate protection for installation in Saudi Arabia's unconditioned basement and ground-floor service areas, where dust and occasional surface water ingress are common concerns for electrical panel longevity.

In Saudi Arabia's commercial and residential construction sector, the Grundfos MTC compact booster range addresses a specific segment of the market: mid-size buildings (four to eight floors) with moderate simultaneous water demand where the cost and space of a full Hydro MPC multi-pump booster set is not justified, but a single pump cannot provide adequate redundancy for 24-hour continuous occupancy. This covers the large stock of Saudi mid-rise apartments, commercial office buildings, small hotels, and light industrial service buildings in secondary cities across Riyadh, Jeddah, Madinah, Makkah, Dammam, Khobar, Tabuk, and Abha. Razz Middle East finds the MTC range consistently specified by Saudi MEP contractors as a cost-effective and space-efficient standard for mid-rise commercial building water supply, with the factory-tested assembly and pre-set controller significantly reducing on-site commissioning time against custom-assembled pump sets.

Razz Middle East stocks the Grundfos MTC range across common pump variants and delivers to all Saudi regions with same-week availability on standard configurations. We provide MEP contractor pricing, installation advisory support, and post-commissioning service for MTC booster systems, and can supply extended warranties and annual maintenance contracts for building facilities management clients.
