Designed for refuse truck hydraulic systems, the Permco Versa-Pak Refuse Pump delivers reliable performance through a combination of robust mechanical construction and integrated valve control options. Key pump features include 25% longer idler gear bearings to reduce shaft deflection, a sealed outboard bearing with a protective shield against contamination, dowel pin construction, and a solid one-piece gear and shaft set.
The Versa-Pak system supports two primary configurations. In a Dry Valve setup, the valve acts as a pressure-compensated flow control, limiting flow to a preset level and returning excess flow to tank at low pressure, reducing wear from overspeeding and overpressurizing while minimizing heat buildup during idle periods. In an Unloader configuration, 100% of flow is diverted back to tank at extremely low pressure when the hydraulic circuit is not in use. Dry Valve models include a built-in bleed valve in the rear cover and are operated via a dash-mounted electric over air switch or manual air valve, including breather vent, tubing, and fittings.

Question by: Wayne F on Jun 1, 2025, 9:50 PM
What's the difference between running this pump in a dry valve setup versus the unloader setup, and which one's better for a truck that sits idle a lot?
Answer by: Customer Support on Jun 3, 2025, 11:04 AM
Good question to work through before you commit to a configuration. In a dry valve setup, the valve acts as a pressure-compensated flow control, so it lets a preset amount of flow reach the hydraulic system and sends the excess back to tank at low pressure. That's real useful for keeping heat from building up when the system isn't actively working, which matters a lot on a truck that spends chunks of time idling. The unloader setup takes it a step further by routing 100% of flow back to tank at extremely low pressure whenever the hydraulic circuit isn't needed. Both reduce wear from overspeeding and overpressurizing, but if your truck idles frequently and you want the least possible heat and pressure load on the system during those windows, the unloader configuration is generally the more aggressive approach for that use case.

trying to decide between the dry valve setup and the unloader setup, what’s the real difference when the truck’s not running the hydraulics?
Answer by: Customer Support on Mar 22, 2026, 11:25 AM
When the circuit is not being used, the Unloader configuration sends 100% of the pump flow back to tank at extremely low pressure. With the Dry Valve configuration, the valve works like a pressure compensated flow control. It limits flow to a preset amount for the system and returns the extra flow to tank at low pressure, which helps cut down on heat buildup during idle and reduces wear tied to overspeeding and overpressurizing.
