webster yb hydraulic pump quotation

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.

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.
