www.ivek.comNov 03, 2021 · The Multiplex series use a single motor and two lead-screws to simultaneously drive multiple three-piece ceramic pump modules. The motor and lead-screw combination drive the pistons in a linear motion to create displacement. Each Pump Module has an air driven rotary actuator to turn the valve towards the intake or discharge port.

A helix is the curve defined by moving a point with uniform angular and linear velocity around an axis. The distance the point moves linear (parallel to the axis) in one revolution is referred to as pitch or lead.

home.iitk.ac.inCharacteristics of ball screws • High mechanical efficiency In ball screws, about 90% or more of the force used to rotate the screw shaft can be converted to the force to move the ball nut. Since friction loss is extremely low, the amount of force used to rotate the screw shaft is as low as one third of that needed for the acme thread lead screw.
