Pop-Off Valves: Their function and proper pressure setting
Have you ever wondered what a pop-off valve is and why you need one? Have you ever needed to set or adjust a pop-off valve? Check out our Troubleshooting Tips video for pop-off valves for critical information on why and when to use a pop-off valve and how to set their pressure properly.
Cat Pumps drive-ends have a reputation for being the longest-lasting, most durable pump drive-ends on the market. After decades of use, or through oil contamination of the drive-end, oil can sometimes leak past the seals. Typically, the proper method of replacing crankcase oil seals is complicated and involves removing the two bearing covers, the crankshaft and bearings, and the plunger rod and connecting rod assemblies before finally removing the oil seals. This method is time-consuming but prevents scoring of the plunger rods when using a sharp pick to remove the oil seals.
