Voith Turbo

Voith turbo logo

Progressive Power & Control sells internal gear pumps, high pressure gear pumps, low-viscosity fluid pumps, multiple flow pumps from Voith Turbo. Voith Turbo purchased H+L Hydraulik GmbH & Co. KG formerly known as Hartmann+Lämmle GmbH Co. KG, enhancing the Voith hydraulic component offerings with the VTHL (or VT H+L) hydraulics division to serve mobile hydraulics and industrial hydraulic customers.

Voith pumps are also used in many manufactured systems. Rather than pay the "upcharge" from the manufacturer, we can frequently provide you with the exact Voith replacement component you need for your equipment.

Some examples are:

  • Krauss Maffei injection molding machinery
  • Husky injection molding machinery
  • Engle injection molding machinery
  • Kautex blow molding machinery

Voith Internal Gear Pumps

Voith internal gear pumps allow you to save space in your machine. The high rates of efficiency, thanks to gap compensation, allow efficient operation, and the optimized pressure progressions ensure low pump flow and pressure pulsations in your hydraulic system. This, combined with a compact force guide inside the Voith internal gear pump, reduces noise emissions so you can more easily meet the ever tightening workplace regulations on sound output.

Voith’s technology creates hydraulic pumps that are quiet, compact and have minimal pressure pulsations while operating at high efficiency.

Voith IP Pump Design:

Both the high-pressure and medium-pressure Voith IP pumps share similar design features, including radial compensation, axial compensation, internal gearing and plain bearings which ensure a smooth flow with minimal pulsation. IP pumps can be combined to create systems with multiple flows.

Internal gear rotation draws hydraulic oil or other pressure fluid into the area between the pinion gear and the internal gear. Radially, the gear chambers are closed by the gear teeth meshing. Pressure fluid is displaced when the tooth heads enter the gaps between gear teeth. The axial plates seal the pressure chamber with the minimal possible gap, reducing volume loss and increasing efficiency.

VOITH IP Multi-flow Pumps/Combination Pumps

Voith IP pumps of the same or different sizes can be combined to form multiple-flow pumps. All sizes of Voith multi-flow pumps are available as two or three-flow pumps, and as four-flow pumps by custom order.

Voith Hydraulic Valves

Voith Directional Control Valves

Directional control fast pilot valves make switching times possible, over 50% faster than direct-controlled valves. Switching time adjustment, stroke limiter and monitoring are available as options. Voith Turbo Hydraulics offers special equipment with standard directional control valves. Due to the compact building design with standing magnet (double solenoid coil with 4/3 valves) the valves can be integrated even in the smallest fitting spaces.

Voith Flow Control Valves

Voith Turbo hydraulic flow control valves are pressure compensated in the millisecond range, and changes in viscosity do not influence the flow rate.

Voith Pressure Control Valves

Direct-controlled Voith Turbo pressure control valves are constructed in seat or piston design. The pressure control valve cartridges can be built directly into control blocks. Voith accumulator charging valves with constant switching limit and soft switching are particularly suitable for drive systems. Use memory load valves to design the installed drive power for the average need. All pressure control valves can be equipped with a gauge connecting valve.

Sandwich Plate Valves

The combination of structure and intermediate plate devices permits the realization of control units with many functions in a small space. The control paths and thus the oil columns are kept very short, a necessary condition for good dynamic behavior of the hydraulic control.

Voith Pressure Relief Valves

Pressure relief valves, type DBV, are capable of controlling and limiting the operating pressure and the flow rate in a hydraulic system. Independent of the set maximum operating pressure, the valve can switch to pressure-free circulation hydraulically, electromagnetically or via an external control oil connection.

The pressure relief valves DBV 50/60 switch the flow on and off depending on the pressure (hysteresis normally set to 10% of system pressure). To allow direct attachment to hydraulic pumps, and especially Voith IP pumps, the pressure relief valves are available with SAE flange connections in 4 sizes (10, 16, 25, 32 mm). The installation orientation can be freely selected.

Electro-hydraulic Amplifiers

VTHL electro-hydraulic amplifiers are numerically controlled precision drives. They consist of the set value input assembly, follow-up control valve and the actuator, which can be either a cylinder or a hydraulic motor. Actuator and follow-up control valve are linked by mechanical feedback. Electric low-power set value input combined with a hydraulic actuator result in high power density, low energy consumption, and high closed-loop gain. The electronic controls are coordinated with the special requirements of electro-hydraulic amplifiers. Interface modules make interfacing possible to all kinds of machine controls.

Voith EPAI Hybrid Motor/Pump Combination

Voith Turbo has succeeded in integrating the well-established internal gear pumps, type IPM (medium pressure, up to 175 bar) and type IPV (high pressure, up to 330 bar) in an asynchronous electric motor. With that an electro-hydraulic unit is available which is very compact in design while also ensuring remarkable low noise emissions. Variable flow from fixed displacement pumps, electric motor - pump - aggregate (with frequency inverter)


The EPA/EPAF Voith internal gear pump or pump combinations generate pressure and volume flow. Asynchronous motor to drive the pump. Frequency inverter for controlling the speed of the motor. EPA/EPAF units can be created with all Voith internal gear pumps

EPAF Voith Turbo for the delivery of cooling lubricants

The EPAF variable-speed motor pump unit with the internal gear pump which was specially developed for the delivery of low-viscosity media. Due to its renowned high efficiency, the IPME pump type is particularly suited as a delivery pump for the cooling lubricant circuit in machines with internally cooled tools. A pressure-dependent drive speed control allows cooling lubricant to be delivered as and when it is required. Pressures up to 100 bar can be generated.

Voith Hydraulic Power Packs

VTHL hydraulic units guarantee your pressure supply. With Voith's accumulator charging technique you generate exactly as much hydraulic energy as demanded by the process. The momentary available volume flow, dependent on the selected accumulator size, will be a multiple of the actually installed pump volume capacity.
