Description

Overview

This yb pump bypass spring is the replacement part for the bypass (relief) valve in YB-series vane pumps. It comes in variants for the YB50, YB65, YB80 and YB100, so tell us which pump you run when you order.

A weak or broken bypass spring lets fuel leak past the valve, so the pump loses pressure and delivery drops. Swapping the spring is a ten-minute job with basic tools. Keep one in the workshop next to a Cube-Smart tags, 5-pack and a plastic fuel indicator, and see the wider fuel station accessories range for flanges and fittings.

Where it works

Mines in Mpumalanga and Limpopo run their YB pumps for long shifts, and the bypass spring is one of the first wear items. Fuel depots in Gauteng and KZN keep spares so a pump failure does not stop a fleet. Farms in the Free State with a YB pump on the diesel tank can service it before the planting season instead of during it. A yb pump bypass spring costs a fraction of a new pump, and having it on the shelf turns a breakdown into a short service. If you run more than one pump size on site, order a spring per size so you are never guessing at the counter.

Questions about this product

Which YB pump sizes does this spring fit?

It is made for the YB50, YB65, YB80 and YB100 vane pumps, with a variant for each. Send us your pump size or a photo of the data plate and we will make sure you receive the right variant before it ships.

How do I know the bypass spring is worn?

Signs are low delivery pressure, a pump that struggles on longer hoses, or fuel noise from the bypass valve. If the spring is short, rusty or cracked, replace it. Fit the matching size only, because pressure setting depends on the spring.
