Operating range, hydraulic coverage Operating pressure: Up to 275 psi (19 bar), depending on temperature. Pump standstill vacuum permissible depending on temperature and pump specification. Operating temperature: From -20 to 360 °F (-30 °C to 180 °C), depending on configuration and pressure. Solids containing liquids: When solids containing media are pumped, flushing of bearings can be carried out using an external sealing liquid.

The MNKA in detail: built for outstanding service life Optional SAFEGLIDE^ PLUS silicon carbide (SSiC) sleeve bearings provide dry-run capability. That helps to overcome short-term upsets and gives valuable time to make corrections before pump damage occurs (see separate brochure). Radial rubbing safety ring ("bump ring”): no danger for the containment shell even in the unlikely event of a failure of the ball bearings. Shown: optionr'-------— Tough all-metal external pump casing absorbs hydraulic loads and those from suction and discharge piping. Unlike non-armoured plastic pumps, no...
