Hand pumps are manually operated pumps and are used in various countries and industries around the world such as marine, industrial, leisure and irrigation. Although it may seem time consuming and unnecessary, hand pumps do have their place within different applications, and are used when pumping is not a continuous activity.
Within industries, hydraulic hand pumps are used for the testing and calibrating of pressure instruments such as transmitters and gauges, and are essential within energy production, health care, construction and wastewater management industries. They are important for ensuring safety and efficiency.
Hydraulic hand pumps take mechanical energy and changes it into hydraulic energy. The handle leverages the internal piston which then forces the hydraulic fluid into the cylinder port. This supplies the pressure that is used for testing, adjusting and calibrating different types of measuring instruments. Hydraulic hand pumps offer many benefits which include efficiency, precision and stability. Hydraulic pressure transfers energy efficiently and allows you to reach high levels of pressure with little effort. Precision is needed when fine tuning is needed. Hydraulic hand pumps are mostly designed with fine adjustment knobs that can allow for pressure to be applied to within .01psi or .069kPa. And, lastly, these hand pumps are made with either cast or machined metal which limits leaks, prevents maintenance and ensures temperature and pressure stability.
Power Team SA supplies a range of hand pumps that are suitable for single or double acting cylinders. The construction of these pumps makes them also suitable for activities during welding applications, and its design also allows it to automatically change into high pressure mode when it comes into contact with the load.
This range of hand pumps has features that ensure safe operation, including a formed metal handle design that minimises handle flex which helps to reduce operator fatigue; a check valve placed downstream from the tamper-proof relief valve which prevents load creep through the full pressure range; the pressure release valve knobs provide increased control when releasing and lowering the loads; and, the pressure release seals in the filler cap design provides a safety valve which prevents over-pressurising the reservoir.
Power Team SA has decades of experience within the hydraulic industry and can offer their expert opinion as well as quality hydraulic products to aid with all hydraulic system and components needs.
