Woerner

Woerner is a renowned German manufacturer of central lubrication systems and progressive lubrication technology that has been delivering reliable lubrication solutions for industrial machines and machine tools worldwide for decades. The company, based in Germany, has specialized in progressive and single-line lubrication systems used for centralized and automatic lubrication of bearings, guideways, gearboxes, and other wear-sensitive machine components.

The core product of Woerner are the progressive distributor blocks of the VPA and VPB series. The VPA series are primary progressive distributor blocks connected directly to the lubrication pump outlet that progressively distribute the lubricant to the individual delivery locations. The VPB series are secondary blocks connecting to the VPA outlet for further splitting of the lubricant to individual lubrication points. Through the progressive action of the pistons, each lubrication point is served consecutively and in a fixed sequence, enabling direct visual monitoring of lubrication operation via the control indicator that stops if a lubrication point becomes blocked.

For driving the distributor blocks, Woerner supplies the GMA and GMG gear pumps designed for use with oil and liquid grease. The GMA series are compact pumps with low flow for small lubrication installations. The GMG series are more powerful pumps for larger installations with multiple lubrication points and longer line lengths. The pumps are available with electric drives for 230V and 400V mains voltage, and in manual operation variants for periodic lubrication.

The Woerner product range further includes plunger lubrication pumps for higher pressure in grease lubrication, electromechanical and electronic lubrication timers for automatically setting lubrication interval and lubrication time, lubrication fittings and couplings, lubrication lines in steel and plastic, and the associated control indicators and signal devices for monitoring lubrication operation. For machine tools, complete lubrication system kits are available containing all necessary components for a complete new central lubrication installation.

Verkopershulp.nl supplies original Woerner lubrication system parts with short delivery times for maintenance and repair of existing Woerner lubrication installations. Our lubrication system specialists help you choose the correct VPA/VPB distributor blocks, the appropriate pump, and the correct lubrication timer for your specific machine and lubricant.

History

Woerner was founded in Germany as a manufacturer of central lubrication systems and over the years developed a comprehensive program of progressive lubrication technology for the manufacturing industry. The company distinguished itself through the reliability and controllability of its progressive distribution systems, where blocked lubrication points are immediately detectable via the control indicators. Woerner built a strong reputation among machine tool manufacturers, press manufacturers, and maintenance specialists throughout Europe and supplies lubrication systems to leading manufacturing companies worldwide. The company continuously invests in further development of electronically controlled lubrication technology for integration into modern machine monitoring systems.

Frequently Asked Questions

How does the progressive distribution principle of Woerner VPA/VPB blocks work?
In a Woerner progressive distributor block, multiple pistons are connected in series. The pressure from the lubrication pump pushes the first piston down, which displaces lubricant to outlet 1 and simultaneously activates the second piston. This sequence continues until all pistons have completed one full cycle. Only then does the cycle restart. Through this operation, each lubrication point is guaranteed to be served and blockage of one point is visible because the control indicator stops moving.
What is the difference between Woerner VPA and VPB distributor blocks?
VPA blocks are primary distributor blocks that connect directly to the lubrication pump outlet. They distribute the lubricant to multiple secondary circuits or lubrication points. VPB blocks are secondary distributor blocks that connect to one outlet of a VPA block and further divide this circuit to multiple individual lubrication points. By combining VPA and VPB you can serve a large number of lubrication points from one central pump.
Which lubricants are suitable for Woerner lubrication systems?
Woerner lubrication systems are suitable for lubricating oil (ISO VG 32 to 460), fluid grease (NLGI 000 and 00), and thin pastes. For standard lubricants with viscosity up to approximately 1000 cSt, the GMA/GMG gear pumps are suitable. For thicker grease (NLGI 1 and 2), the Woerner plunger pumps are the correct choice. Consult the lubrication specification of your machine for the recommended viscosity class.
How do I replace an element of a Woerner VPB distributor block?
Release the lubrication pressure by switching off the pump and venting the pressure. Disconnect the lubrication lines on the relevant block. Remove the locking screw from the defective element and pull the element out of the block body. Inspect the block channel for contamination and clean if necessary. Insert the new element and tighten the locking screw to the specified torque. Restore the lines and test the lubrication cycle at low pressure for leak-free operation.
Can I expand a Woerner lubrication installation with additional lubrication points?
Yes, progressive Woerner lubrication installations are modularly expandable. Additional VPB secondary blocks can be mounted on available VPA outlets. If all VPA outlets are occupied, a larger VPA block with more outlets can be installed. When expanding, consider the pump pressure and pump volume: each additional lubrication point increases the required system flow throughput.
How do I set the lubrication interval on a Woerner electromechanical timer?
Woerner electromechanical lubrication timers have two separately adjustable times: the pause time (interval between lubrication cycles) and the pump active time (duration of the lubrication cycle). Both are set via rotary switches or DIP switches, depending on the timer model. The pause time typically varies from 2 minutes to 8 hours. The pump active time varies from a few seconds to a few minutes. Consult the machine manual for the recommended lubrication interval.
Does Verkopershulp.nl supply complete Woerner lubrication installations for machine tools?
Yes, Verkopershulp.nl can assemble a complete lubrication system based on your machine specifications, including Woerner GMA/GMG pump, VPA primary distributor block, VPB secondary blocks, lubrication lines, lubrication timer, and monitoring devices. Specify the machine type, number of lubrication points, line lengths, and lubricant for a complete custom offer.
Are Woerner distributor blocks compatible with those of other manufacturers?
Woerner VPA and VPB distributor blocks in many cases follow the same external dimensions and connection patterns as comparable progressive distributor blocks from Lincoln, SKF Vogel, and other European manufacturers. However, interchangeability is not guaranteed without measuring the exact dimensions. Our specialists compare the technical data of the existing block with the Woerner range to confirm interchangeability.
