Water - Hypertherm HyPrecision 15 Operator's Manual

Water

Do not use deionized water unless the system has stainless steel water fittings. Using deionized water in
standard systems can cause the plumbing parts to fail and causes substantially shorter consumable life.
Check local codes to determine if a backflow prevention valve is required to separate the pump from the
facility's potable water.
If the cooling and cutting water temperature is higher than 24°C (75°F), cool the water before use. Water
that is too warm is inefficient for cooling and can reduce high-pressure seal life.

For minimum and maximum flow, pressure, and temperature requirements, refer to the Pump specifications section,
which begins on page 165.
Water quality
The quality of the water supplied to the intensifier has a direct effect on the life of pump parts. Poor water quality
increases operating costs by causing unnecessary wear on pump parts and shortening maintenance intervals.
Before installing the system, have a water quality analysis done. Water quality reports that show pH, silica, and hardness
levels are frequently available for no charge from local public utility suppliers.
Total suspended solids (TSS)
Suspended solids refers to small, solid particles that are suspended in water. Filters are used to remove these solids.
Hypertherm pumps include water filters that remove TSS from the cutting water.
Total dissolved solids (TDS)
Dissolved solids refers to molecular, ionized, or microgranular particles in solution in water. TDS include hard elements
such as iron, calcium, magnesium, and silica, which form deposits on the inside of high-pressure plumbing and can
damage check valves, seals, orifices, and other consumables.
Most systems require softened water. Consult a specialist for recommendations when choosing a water treatment
system.

Reverse osmosis systems are available from Hypertherm.
