General Pump Unloader Mounting Blocks
Unloader mounting blocks from General Pump
increase the durability of your pressure washer and provide flexibility when mounting unloaders and other accessories to your high pressure cleaning system. These simple plumbing devices are a favorite among commercial and industrial pressure washer manufacturers, as well as custom pressure washer builders and mobile contract cleaners.
Rather than mounting a trapped pressure unloader valve
or flow sensitive unloader valve
directly to the pump head, these unloader valve mounting blocks allow you to secure the unloader to the frame of the unit. Typically, the discharge port on the pump is then plumbed to the mounting block with a high pressure jumper hose
rather than hard plumbing fittings. This minimizes physical stress on the pump manifold discharge port and reduces the chances of catching something on the unloader valve and breaking plumbing fittings or damaging the pump manifold itself.
These plated steel manifold blocks come in 3/8 in (female NPT) and 1/2 in (female NPT) port configurations. They also include bolts for direct mounting to a pressure washer frame or control panel. Pressure-Washer-Parts.com keeps plenty of both block sizes in stock and ready to ship with any order. Please contact us
