M.A.H.Y. Khoory Trading & Projects

Turning World-Class Products Into Building Performance

About M.A.H.Y. Khoory Trading & Projects

M.A.H.Y. Khoory Trading & Projects is the M.A.H.Y. Khoory Group’s engineering and distribution business. Bringing together specialist trading companies, leading international technologies and decades of engineering expertise, it delivers integrated solutions for building and infrastructure performance across residential, commercial, industrial, utility and agricultural projects in the UAE. Its capabilities span pumping, water and wastewater systems, odour control, HVAC, water heating, valves, tools and equipment, and extend well beyond product supply to engineering, project support, fabrication, workshop services and lifecycle support.

It is built on a clear principle: the right system begins with the right selection, long before any equipment is supplied.

The business grew out of the Group’s earliest pump agencies, which supplied the farms and wells of the UAE. As groundwater levels dropped to around 300 feet, the Group introduced electric submersible pumps capable of drawing water from depths of up to 1,000 feet, in place of the old diesel-powered motors. The Group has now been an authorised Grundfos distributor for more than five decades, and its portfolio has grown to include some of the world’s most respected manufacturers.

Today, the business works in three ways. Trading supplies products from stock in the UAE, for budgets and project requirements of every size. Projects turns the same equipment into engineered solutions, from villas to complex landmark developments, deciding which system a building needs, how many units and how they are arranged. Both run through four companies, each holding its own principal agencies: M.A.H.Y. Khoory Trading, Emirates International Equipments Machinery (EIEM), Al Mehwar and Greenland Equipment & Machinery. The Group’s Machinery Workshop & Service Centre provides after-sales service, retrofit and lifecycle maintenance, keeping systems running long after handover.

Machinery Workshop & Service Centre

Grundfos Authorized Service Partner
GOLD audit result

The Machinery Workshop & Service Centre provides the after-sales service, retrofit and lifecycle maintenance for Trading & Projects, keeping installed systems running long after handover, with multi-brand pump service for government, hospitality and residential customers across the UAE. As a Grundfos Authorized Service Partner, it holds a GOLD result in its Grundfos service audit. After it took over Dubai Municipality's domestic pumping systems, emergency call-outs fell from around 140 a month to fewer than 10.

Environmental Responsibility In Practice

Pumps and cooling systems run for decades, so the way they are selected and maintained decides how much energy they use over their working life. By sizing systems correctly, specifying efficient technology, assembling equipment locally and keeping installed systems in service for longer, Trading & Projects supports the UAE's ambition for a more resource-efficient and sustainable economy, in line with its decarbonisation goals and the Make it in the Emirates agenda.

Energy

Payback within five years.

Energy audits and pump-system assessments compare what an existing system consumes with what the correct system would. On a project reported by the Al Ain branch, the capital cost of the replacement was recovered within five years.

Variable speed

Output matched to demand.

Variable-speed Grundfos and ESPA pumping systems and Fuji Electric drives adjust output to actual demand, rather than running at full speed regardless of need.

Local value

Assembled in the UAE.

Packaged booster and transfer sets are assembled in the UAE, including Franklin Electric booster sets built under the manufacturer’s authorisation, keeping assembly, testing and engineering capability in the country.

Lifecycle

Repaired, retrofitted, kept in service.

Repair, retrofit and planned maintenance extend the working life of installed equipment. For Dubai Municipality, around 300 domestic pumping systems were restored or replaced with more energy-efficient units.

Engineering Behind Every Selection

Every system is engineered before it is supplied, so the equipment that arrives on site is the equipment the building actually needs.

Engineer presenting a pump layout to a project team

Sized to the building.

Pump Selection and Hydraulic Calculations

Flow, head and pressure losses are calculated for every floor and every bend in the system. Too little pressure leaves the top floor short of water; too much means paying to run a pump the building never needed.

Engineer checking equipment in a plant room

Designed for the shock.

Surge and Steady-State Analysis

When a valve closes quickly, the water behind it keeps moving, and the shock can split a pipe. Surge analysis establishes how severe that pressure will be, so the system can be designed to withstand it.

A basis for replacement.

Energy Audits

An audit measures what an existing pump consumes and what the correct one would, giving owners a clear basis for replacement decisions.

Engineer reviewing technical submittals for a pumping system

Cleared before site.

Technical Submittals and Approvals

Datasheets, selections and compliance statements are prepared for consultant approval, so equipment is cleared before it reaches site.

Assembled and tested in the UAE.

Packaged Systems and Local Assembly

Duty/standby and variable-speed booster and transfer sets are assembled in the UAE with their control panels, vessels and accessories.

Automatic and protected.

Control Panels and Drives

Pump control panels and variable-frequency drives provide automatic operation, protection and speed control, matched to each application.

Engineer commissioning a pumping system on site

Verified before handover.

Testing and Commissioning

Systems supplied on projects are inspected, tested and commissioned on site by the Group's own engineers, and verified against their approved selection.

Engineer reviewing an upgrade to an existing pumping system

Older systems brought up to date.

Retrofit and Lifecycle Service

The Machinery Workshop & Service Centre assesses, modifies and upgrades existing systems, extending their working life and bringing older installations up to current efficiency.

Quality Assured at Every Stage

On a building services project, quality is measured on site and for years afterwards: whether the equipment is approved, whether it performs as selected, and how quickly it is restored when something fails.

Approved Before It Reaches Site

Selections, datasheets and compliance documents are prepared for consultant approval before anything is ordered. At the Al Ain branch, 95% of project submittals are approved.

Safe for Drinking Water

Key pump and pressure-vessel ranges supplied for potable-water systems hold WRAS approval for contact with drinking water, so they can be specified for drinking-water supply with confidence.

Verified Before Handover

On projects, systems are inspected, tested and commissioned on site by the Group's own engineers, and checked against the selection the consultant approved.

Parts Already in the Country

Equipment and fast-moving spare parts are held in the UAE, including genuine Grundfos parts in Dubai and Hisense air-conditioning stock worth more than AED 5 million, so replacements can be supplied from local stock.

Response Within Hours

Maintenance customers receive a 2–4 hour emergency response. On Dubai Municipality's domestic pumping systems, call-outs fell from around 140 a month to fewer than 10.

Audited to the Manufacturer's Standard

The Service Centre is audited by SGS for the Grundfos Global Service Network, covering facilities and people, environmental practice, ISO certification and health and safety, and holds a GOLD result.

One Point of Accountability

Trading & Projects can select, supply, commission and maintain a system itself, so responsibility stays in one place after handover.
