webster yb hydraulic pump brands

The YB Series offers a complete range of compact and powerful hydraulic gear pumps and motors, in flows from 1 to 6 gallons (3,8 to 22,7 liters). They are ideal for applications where a lightweight pump or motor is required. Included in the YB Series are hydraulic pumps, unidirectional hydraulic motors and birotational hydraulic motors.

Because of their compact size and low weight, YB Series hydraulic gear pumps and motors are often specified whenever space and weight are limitations. Typical applications include: lawn and turf equipment, fan drive systems, lift tables and small, off-highway machinery.

Words like superior, quality, high performance are synonymous with the Webster brand. The highly coveted Webster brand was sold and acquired multiple times, Sauer-Danfoss supplied OEM Webster components for years until about 15 years ago when they stopped supplying the B series.

Hydraulic.net worked with Webster in the early years and was a preferred provider for distributors, repair shops, and end-users for Webster pumps. Specializing in providing pumps that are obsolete in the marketplace or hard to find pumps, Hydraulic.net was the top choice then and continues to be today.

B Series pumps have a maximum operating speed of 2000-3500 rpm, depending on pump displacement and pressure. This is based on operation at sea level using SAE oil with a viscosity of 175 SUS (36 cSt) at 120°F (48,8° C). Actual limits for each displacement can be found in the pump performance curves. Minimum speed for the B Series is 500 rpm. This is the normal minimum speed at which the pump will operate continuously at rated pressure.

B Series pumps are designed to operate continuously at the rated pressures shown. In most applications, this maximum pressure should be considered the maximum relief valve setting. Lower operating pressures will extend the life of the unit.

Below are some product numbers for B series pumps. Often, people may have the model or serial number; we can cross reference those numbers as well. Call one of our helpful hydraulic experts or email a quote request, providing the numbers from your pump and we will help! We try to provide an accurate quote within 30 minutes in some cases it may be longer as we are confirming timing and ensuring we are setting realistic expectations. Many of the Webster pumps are in stock regularly and able to ship in 24-48 hours. Our goal is to get you back up and running ASAP!

Webster/Webtec manufactures hydraulic flow controls, pressure control valves and directional control valves for mobile machinery. We offer choices of threading and port size for standard or custom specifications. We offer replacements for Webster gear pumps, Milwaukee cylinders, and Teledyne valves.

The ILFC is a pressure compensated flow control valve (fixed, in-line) with 2 ports. Can be used to maintain the flow rate of hydraulic fluid for operating cylinders and motors at a constant speed.

Fixed priority flow dividers allow you to split a single input flow into a regulated flow and an excess flow. The regulated (Priority) flow can be used to perform the required task while the excess flow which can be routed directly back to the oil reservoir or redirected to drive another system, which can eliminate the need for an additional pump to drive an ancillary system. This is a 3-port flow divider which is pressure compensated and contains an on-board relief valve.

Priority Type Flow Dividers split a single input flow into a Priority flow which is a regulated flow, and a bypass flow, which is excess flow. The excess bypass flow can can be rerouted to the hydraulic fluid reservoir or used to power a second system, which can eliminate the need for a second pump to drive another hydraulic circuit. Easy adjustments to the priority flow can be made visually using a hand dial. Pressure compensation allows both flows (priority and bypass) to be controlled concurrently at their own pressures without changing the flow rate of the priority flow.

A great choice for agricultural and industrial uses, as this remote control flow divider is vibration and contamination resistant and can be powered from a vehicle supply using the on-board 9 - 28 V D.C. supply. Current draw is automatically limited to avoid overheating or motor overload. Model FDM offers a low-cost method of controlling the speed of a hydraulic motor. The regulated (priority) flow port gives an output free of affect by load pressure while the bypass port can be directed to power a secondary hydraulic circuit. Remote control use from up to 130 feet is possible using a potentiometer.

Allows the flow to be diverted mechanically by an offset spring pushing the spool. The spool and spring are contained in a sealed housing to prevent environmental corrosion. Available in one spool or two spool versions. The 2-spool version allows you to divert flow from one circuit to another or to a hydraulic fluid reservoir. A wide variety of spool ends and port threading are available.

A rotary spool type directional control valve which contains a rotor that rotates relative to body of the valve. Inlet and outlet ports can be connected in many different flow patterns to control pressurized fluid for start, stop or directional changes. Webster’s flat rotors compensate for valve wear, creating near zero-leak through the life of the valve. Available with 7 different flow patterns, 3 flow ratings and several porting options. These valves may be mounted on a manifold, on a panel or used inline on the hydraulic circuit. Manual control is achieved using ball handles, spring centring and detents.

Durable hydraulic directional control valve used for mobile and industrial systems. Minimal leakage in the spool even under the 3625 psi pressure tank port rating. Methods of operation include lever, cam and pilot (air or oil).

Pressure relief valves protect hydraulic circuits from overload by limiting maximum pressure to a pre-set capacity. The relief pressure setting is set by Webster to the customers specifications within pressures from 290 psi to 3000psi. The fast response of this valve protects the hydraulic circuit from shock and overload or the expansion of thermal fluids. Due to straight-through porting, the valve can be connected inline using a “T” connector. Model RV020 direct acting in-line relief valve is minimally affected by particle contamination

Gear hydraulic pump is ideal for use on equipment in the mobile, agricultural, construction, and mining industries. Also suitable for PTO pumps, machine tools, refuse haulers and compacting equipment.

Equipped with bi-directional check valves, the Chief MH Series series features small displacement and high pressure ratings. The MH series Pump/motors have an aluminum body with cast iron flange construction, and case drain. Available displacements range .065 to.517cu.in/rev. Similar to MTE “D” series and Sauer-Danfoss Webster YB series.

The true depth of our knowledge lies within the diagnosis and repair of hydraulic pumps and other hydraulic products. Whether we have your unit in stock or not, the repair is always an option. In fact, it may be your best option for obsolete and hard to find hydraulic pumps, motors, valves, and servos.

Hydraulic pump is a Webster YB series pump, model 29YB, 2000psi and 4000 rpm max. Actual 3d diagram and all motor specs at this link: Webster B Series Hydraulic Gear Pumps, Hydraulic Gear Motors, Unirotational Pumps and Motors, Birotational Pumps and Motors

Pump model number is: 29YBADO12-2LB, this pump was built by Webster, but I guess Sauer-Danfoss took over making parts for it awhile ago because it is out of production. Now, Quality Control Corp., as of 2010, has acquired the Webster B, YB, and YC series and manufactures all parts and complete replacement pumps.

Now for the good part. My pump, running over 4000 rpm for over a year with the pulley conversion to increase ground speed, and a rental unit originally to boot, has gears and bearing with hardly any wear according to the professional hydraulic mechanic I hired to fix my machine. The inner seal assembley (black oval seal about 2" across) had "cavitated", and was missing an 1/8th inch chunk allowing high pressure to leak back into the low pressure side.

I am attaching the 2 page repair instructions to this post. Don"t replace your motor or buy from Vermeer, $82 and my pump will be like new! Also, looks very easy to do even though I hired a mechanic to do it cause he has flow meter, line plugs, and TIME!

Hope this helps everyone because I could not find one thing on the internet about a repair kit, only 3 people locally were able to identify the pump and get a price for me (some double others, and still took 2 weeks to get even though told them 2nd day air), and the only links on the internet were to two posts on this forum about part numbers. Now you have it all, diagrams, everything.
