Screw spindles


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 andwatersoluble coolants.
High pressure screw pumps are NOT designed for dry-running.
