HOW IS THE DIFFERENCE BETWEEN HYDRAULIC SPEED VARIATOR AND MECHANICAL VARIATOR? VAR-SPE HYDRAULIC SPEED VARIATORS Many customers ask to us which are the differences between hydraulic and mechanical variator: we thought to create a summary sheet with the main characteristics. VARSPE VARIATORS: Working Principle Var-Spe Hydraulic speed variator has a [...]

VAR-SPE K2 SERIES VAR-SPE SERIE K2 with easy handwheel control for serie HDA chemical injection pump, ensure a minimal chance of failure. Turning the rate adjustment dial of the variator counterclockwise will increase the pump stroke rate. In this type of pumps the variator has been preset to limit rotation [...]

The hydraulic speed variators with electronics control is a SOLUTION for a DOSING PUMP SYSTEM used in TUNNELLING MACHINE.

This is the photo that our Australian distributor sent to us about our variator manufactured in 1992 (27 years old). It has been working in the Cooper Pedy in South Australia in OPAL FIELD screening material on a DRUM.

The variators serie K2 are combined with this pumps and there are supply with ATEX Certification.

The type of pump in the photo is designed for dosing any type of liquid and the variator used is K2 that gives the possibility of reversing the flow of the pump, maintaining at the same time a perfect control on the flow rate.

Our variator K2 serie in this application is combined with a Gear Pump range FG-FZ-FX: these are flanged gear pumps with lantern and coupling suitable for applications of standard engines B3/B14 shape size 71-80-90-100.

In this application, combined with the reducer, the hydraulic motor allows the movement of the carriage.

Very Interesting VAR-SPE application with Radial Piston Motor: is particularly SUGGESTED for application where LOW SPEED IS REQUESTED.
