Pumps
Deritend provides a complete maintenance and repair service package for all types of pumping equipment including round-the-clock emergency breakdown.
Our expertise and first class resources mean that very cost-effective solutions are available to our customers for any application, from boiler circulation equipment or deep well pumps to all types of surface pump. Sectors range between:-
- Water treatment (clean) – deep well bore hole abstraction, pressure boosting, irrigation, river abstraction, fire protection, industrial process
- Water (dirty) – sewage, waste products, building services, sludge and storm water / drainage, industrial effluent
- Petrochemicals
- Fire protection
- Agriculture
Innovative Solutions
Extending the life of any Pumping System is the key element to the work of The Deritend Group. This philosophy is supported by the following services:
- Refurbishment
- Flameproof equipment repair & certification
- Sourcing and retro-fitting obsolete equipment
- Re-designing
- Reverse-engineering
Extending the life of an existing pump or system enables the plant to continue providing an efficient and cost effective process. The repair solutions available to achieve this include:
- Shot blasting
- Sand blasting
- Steam cleaning
- Cryogenic cleaning
- Ultrasonic cleaning
- Metal spraying
- Coded welding
- Spiral welding
- Radiography
- Dynamic balancing
- Laser alignment
- Thermal imaging
- Vibration analysis
- Protective coatings
- Efficiency coatings
Energy losses due to the effect of viscous drag and surface roughness accelerated by wear and corrosion effects, can be reduced by the application of a protective coating to the surfaces of fluid handling equipment. Independent tests show a typical 6% reduction in pump power consumption without changing the characteristics. The benefits are:
- Cost reduction
- Improved hydro dynamic flow
- Reduced maintenance costs in erosion-corrosion situations
Testing
Testing and calibration equipment of the highest quality is on hand at you’re local service centre
- Pump performance testing
- Vibration testing
- Noise testing
- Load testing
- Flameproof certification
Following refurbishment, equipment is tested and calibrated to ensure performance levels meet or in some cases exceed those originally specified by the manufacturer.
The Deritend Group Service Centres are equipped with custom-built testing facilities to put the repaired item through its load conditions and also ensures equipment operates at maximum efficiency.
All the equipment tested is certified and released under The Deritend Group Quality system.
