Screw spindle pumps with their silicon carbide spindle housing and highly wear resistant spindles are capable of achieving extremely high pressures.
Brinkmann high pressure screw pumps are designed for pumping filtered and lubricating fluids such as coolant oils and watersoluble coolants.
High pressure screw pumps are NOT designed for dry-running.

1) QTh: Theoretical flow rate
Viscosity > 90 SSU more power consumption.
All 6 series screw pumps with an operating flow rate of 210 GPM / 800 l/min or above must be operated with a feed pump which supplies fluid with at least 14.5 psi / 1 bar of pressure to the pump inlet.
