Advanced Workholding Pump
A HIGHER STANDARD FOR WORKHOLDING
The Advanced Workholding Pump was specifically designed for fixture workholding. This efficient 2-stage pump easily stands up to high demand circuits. There are no duty cycle limitations because the VFD (Variable Frequency Drive) protects itself from overheating. The VFD also removes any concerns for international electrical service inputs, offering a full range of options. Electrically efficient by design, the pump uses an electronic digital pressure switch setting for the on-demand function. These features combine to create an extremely low carbon footprint. At the core of the Advanced Workholding Pump is a state-of-the-art rotating group pump. This multi-piston radial pump generates sufficient flow to power multiple fixture circuits. The 5-gallon reservoir supplies 3.5 gallons of usable oil to provide ample volume to actuate more clamping devices and can easily feed 1 to 6 circuits. Save Hundreds on Energy - Only Runs on Demand! Advanced Workholding Pump
What makes the Advanced Workholding Pump so advanced?
First, it uses the latest in premium efficiency electric motor technology - Variable Frequency Drive (VFD) to control its electric motor. What does this do and why is it important? It starts the motor by varying both current and frequency allowing a motor to “spin up” rather than surge when started by a direct motor starter. This reduces the in-rush current and the heat that must be dissipated by a motor starting frequently. It also allows the motor speed to be reduced as it comes close to the projected end-of-run. This is accomplished by analog output from the pump pressure switch that “tells” the VFD control to begin slowing down as it gets close to its set point. This slows the motor from its maximum of 1740 rpm as it approaches the set point of the switch. Older contactor driven pumps are spinning at full rpm when switched off and can often result in pressure “over-runs” as the motor coasts to a stop after the loss of power. Second, it uses the latest technology in electronic pressure switches to communicate directly with the VFD controller to start and stop the motor.
Why is this important? It has two adjustable set points that you define specific to your application. Set Point 1, or SP1, defines how high the pump builds pressure to and then the motor turns off. When a circuit is called on to actuate and pump manifold oil pressure is needed, the pressure switch reacts by dropping, this reaction trips the reset point, or RPI. This communication with the VFD will run the motor back up and serve any and all circuit needs until satisfying SP1 and then it rests again. The on-demand feature greatly reduces power consumption and unwanted hot oil, both are valuable benefits. Additional pressure switches can be added to individual circuits at pump mounted directional control valve locations. These can provide a confirmation feedback loop to a machine controller when monitoring for a minimum acceptable individual circuit pressure within machine control logic. Third, the advanced 2 stage pump design uses two flow rates to power your system with an economical 1HP or 2HP motor rather than a 3 HP or larger motor, which would be required with a single stage pump. It uses positive displacement pistons to provide the low pressure - high flow fluid to position cylinders quickly, as well as the high pressure - low flow fluid at the end of the cycle. The pistons, providing both low and high flow, are positive displacement and will never reduce their output flow - unlike gear and gerotor pumps which will lose performance over time. Finally, it can be used as a “pendant controlled pump” or with a “machine tool interface cable” to allow the machine to control and monitor the pump. Our Customer Support Specialists can help you choose options to configure the pump EXACTLY as you require. Once the pump part number is determined, you can reorder easily and quickly any time you want the EXACT CONFIGURATION repeated.
Two Motor Sizes to Suit Your Needs. The Advanced Workholding Pump 1HP features a 1HP motor and a 2HP motor energizes the Advanced Workholding Pump 2HP. If clamping speed is a concern, we recommend that you calculate your system’s oil volume to determine if you require a 2 HP pump. To aid in your pump selection, Vektek has developed “Convenience Packages” that include the most popular configurations. If your application falls outside these convenience packages, call us --we are here to help.

Standard 1-4 Valve Machine Tool Interface Control (without power)
INTERFACE Machine Tool Interface Control Operated Pump Complete integration of the pump and valve control to the CNC machine can be accomplished with 1 of 3 options, all using the Harting Series Han 10B connector system in a single 16 ft (5M) cable. The Harting Series Han 10B connector utilizes A, B, or C modules with 12 pins each to connect valve control, pressure switch monitoring, and pump status monitoring. In the standard 1-4 valve or 5-6 valve system, power for the pump motor is supplied in a separate service cable. In the optimized 1-4 valve system, power for the pump motor is included in the C module of the single machine tool interface cable (5-6 valve not possible). Each system is supplied with a mating female cable receptacle with a 16 ft (5M) pig tail to be mounted and connected to the machine tool controller or PLC (Programmable Logic Controllers). The pump is supplied with a mating male cable receptacle that is already prewired to the pump enclosure for complete control. Input pump status monitoring for each configuration includes oil level, oil temperature, oil filter clog indicator, and VFD fault status. Output from PLC to the pump includes emergency stop and fault rest. This allows for complete control and monitoring of the pump system in all configurations. All Machine Tool Interface Control options must be configured at the time of order and built at the factory. These options cannot be added or upgraded in the field.
