Introduction: MHC’s Commitment to Quality & Efficiency

At Muhamed Harb Contracting (MHC), our motto is “Where Quality Meets Value”. Since our establishment in 2016, we have stood firm in delivering high‑standard electromechanical and finishing works across Egypt, even through challenging global economic and health conditions. Our partnership with leading brands such as Grundfos underscores our emphasis on reliability, performance and integrated service. As the authorized distributor for Grundfos products in Egypt, we bring both the product and the professional support to ensure your project succeeds.
In this article, we focus on how MHC employs the Grundfos SMG series — a world‑class line of horizontal, planetary‑gear driven mixers — and how we integrate that into our contracting work to provide clients with optimized mixing solutions.
Why the SMG Series Matters in Contracting Projects
What is the SMG Series?
The SMG series from Grundfos is a range of submersible/immersed mixers with planetary gear drive, designed for mixing, homogenising and suspension of low‑to‑medium viscosity liquids.
For example:
-
The SMG series covers motor sizes from 0.9 kW up to 18.0 kW.
-
Suitable propeller diameters from 550 mm up to 900 mm, depending on version.
In essence, the SMG provides a flexible, industrial‑grade mixing solution, ideal for tanks, stations, treatment‑plants and other infrastructure projects — exactly the kind of electromechanical scope that MHC engages with.
Key Technical Features of SMG Mixers
When specifying and installing mixing solutions we pay attention to features that guarantee reliability, efficiency and long‑term cost‑effectiveness. The SMG covers many of these:
-
Planetary gear drive for robust torque delivery under submersed conditions.
-
IE3 motor components (high efficiency) and variable speed compatibility.
-
Sealing and bearing systems designed for harsh environments (e.g., two lip seals, ceramic wear bush, mechanical seal).
-
Wide range of installation accessories (stainless‑steel AISI 304/316) for adaptation to different setups.
-
High thrust‑to‑power ratios (for example ~0.268 N/W and up) enabling strong mixing at moderate power.
Typical Applications & Benefits
Why is the SMG series particularly relevant to contracting works in Egypt? Here are application scenarios:
-
Municipal wastewater mixing, sludge suspending & pumping‑station basins.
-
Industrial tanks and basins requiring continuous mixing to avoid sedimentation or to support chemical‑/process‑treatment.
-
Infrastructure projects where mix/flow control is integral to the overall mechanical scope (e.g., power plants, utilities, distribution buildings).
The benefits to MHC’s clients include: -
Improved process stability and reduced downtime.
-
Energy‑efficient motors and drives = lower operating costs.
-
High reliability and long lifecycle = lower maintenance costs.
-
Flexibility in installation = we can integrate into various structural & civil works.
MHC’s Role as Authorized Distributor & Contractor
Partnership with Grundfos
MHC is recognised as an authorised distributor and partner for Grundfos products in Egypt (Industry‑Partner listing).
This relationship means:
-
Access to original SMG units (and accessories) directly via Grundfos.
-
Technical training, documentation and support from Grundfos.
-
A local entity (MHC) handling supply, installation supervision and after‑sales service for these products.
Local Capabilities in Egypt
MHC’s strategic capabilities include:
-
A modern pump‑assembly facility (according to their site) that supports customisation and quick supply.
-
On‑site supervision and technical support during pump/mixer installation (as described on their website) to ensure correct integration.
-
Experience across major Egyptian institutions (e.g., Ministry of Electricity & Renewable Energy, Alexandria University) which gives both credibility and deep local understanding.
MHC’s Service‑Model for SMG Projects
When installing SMG mixers, MHC offers:
-
Site survey and specification advice: ensuring correct model (power/size/propeller) is chosen.
-
Mechanical & electrical installation: ensuring correct mounting, alignment, cabling, protections.
-
Commissioning: verifying performance, vibration, flow, thrust, etc.
-
Maintenance & spare‑parts support: helping the owner operate reliably over the lifecycle.
This service‑model differentiates MHC from simple suppliers — we act as full electromechanical contractor + pump specialist.
How MHC Implements SMG Solutions in Practice
Project Selection & Needs Assessment
The first step is identifying where mixing is required in the broader contracting project. For example: a pumping station for the Canal Electricity Distribution Company may require mixing to keep sediments in suspension. MHC engineers assess: tank geometry, fluid properties, required flow velocities, access for installation, electrical supply constraints.
We then map these to SMG series capabilities: required motor power (0.9–18 kW), propeller diameter, gear‑ratio, installation accessories.
Specification & Sizing
Using data from Grundfos documentation, we size the SMG unit. For example:
-
A model SMG.12.63.275.5.0B has thrust‑to‑power of ~0.403 N/W and axial thrust ~520 N.
-
A larger model SMG.56.86.264.5.1B handles axial force ~1,910 N, flow ~745 l/s, propeller diameter ~860 mm.
We also account for mounting accessories (AISI316 brackets, cables, control panels) and ensure the civil/infrastructure works (access hatches, lifting gear, service platforms) are in place.
Installation and Commissioning
Once delivered, MHC’s team installs:
-
Fixing the motor/gear unit to the support structure, aligning and anchoring properly.
-
Connecting cables (often 3 × 400 V/50 Hz supply). For example that SMG model had 13 A rated current.
-
Verifying motor protection, leak sensor in gearbox (many SMG units include oil‑filled gearbox with leak‑sensor).
-
Running initial test: measuring flow velocity, verifying propeller speed (e.g., 264 rpm in that model) and thrust, checking no vibration or unusual noise.
-
Commissioning documentation: performance data, warranty start, client training on safe operation.
Maintenance & Lifecycle Support
MHC ensures lifecycle value by:
-
Offering scheduled maintenance: checking bearing wear, gearbox oil condition/leak sensor status, propeller condition.
-
Having spare‑parts access via Grundfos + local stock from our assembly facility.
-
Providing troubleshooting and guarantee support: thanks to our authorised‑distributor status.
-
Advising clients on energy optimisation: variable speed drives (VSD) can be used with SMG series to reduce power when full mixing isn’t required.
This comprehensive support aligns with MHC’s promise of “quality meets value”.
