A trade background, not a catalogue
Fluid handling and all the products associated with moving and controlling liquid is our speciality. GSR Mpumalanga was established in 2003 by David Guthrie, a qualified Instrument Mechanician, and has been supplying and installing across Nelspruit and the surrounding areas ever since.
We are a supplier of test, measuring and analytical equipment, and we perform certified pressure, temperature and torque wrench calibrations. Our pump range runs from sewage to irrigation to potable water and solar pumps, working hand in hand with our filtration systems — and we service and repair various types of water pumps.
We service and repair various types of water pumps, and back everything we supply with installation, calibration and ongoing support from our Nelspruit workshop.
Respect. Service. Gratitude.

04 Services
Supplied, installed, calibrated and maintained
We do not stop at the delivery note. The same team that specifies the equipment installs it, commissions it and keeps it running.
Product Supply
We supply fluid handling products, process instrumentation, control systems, pumps, filters, valves, pneumatics and electrical components - sourced from the brands we know and stock.
Installation
Installation of booster pumps, pump control panels, filter systems and remote wireless pump switching systems, carried out by our own team.
Service & Repair
We service and repair various types of water pumps, along with the control gear and panels that run them.
Calibration
Certified pressure, temperature and torque wrench calibrations, traceable to SANS standards. Torque calibration from 0 – 300 Nm.
Maintenance
