Protecting your bottom line and the enviroment! Flow Control/Unloader Refuse Pump System OLD BLUE IS GOING GREEN
n Available in six frame sizes (24-47 GPM @ 1200 RPM) n Wide variety of controlled flow options n Pressures to 3000 PSI n Special design pressure balanced wear plates maintain high pump efficiency throughout all operating ranges n High strength cast iron dowel pin construction n High strength alloy steel gear and shaft set n Sealed outboard bearing protected with an outer seal keeping contamination away from the pump n Built-in non-adjustable pump safety relief valve n All units are 100% factory tested n Improved fuel savings due to lower horsepower draw in the unload mode n No external overspeed components that effect operator control, efficiencies and productivity n Improved route time and increased productivity and profits n No external speed sense connections required n No need for special directional control valves with signal lines n Less system heat generation in the unload mode n No pneumatic components or air line connections required n Tamper-resistant flow regulation, yet field adjustable n Simplistic gear technology design allows for low technical level maintenance training n Continuous oil circulation provides better filtration conditions n Quieter operation than conventional dry valve systems n One piece design provides for simple installation and reduced plumbing connections OLD BLUE IS GOING GREEN The Versa-Pak Flow Control/Unloader unit is ideal for most residential and commercial refuse hydraulic systems. Applications include residential and commercial front loaders, rear loaders, automated side loaders, compactors, roll-offs, recycle and all PTO driven pump applications. The Flow Control/Unloader configuration has both the Flow Control and Unloader function. By flipping a switch on the dash, the operator can go into the Unload mode where full flow is diverted back to the tank at low pressure. This function reduces system heat buildup and horsepower losses resulting in substantial vehicle fuel efficiencies. The priority pressure compensated flow control valve allows a preset amount of flow to the hydraulic system with the excess flow being returned to tank; this function protects the system’s main relief valve from being flooded. In addition,the priority type pressure compensated flow control minimizes heat generation by returning unused oil back to tank. This oil is returned to tank at only a few hundred PSI more than system pressure rather than dumping excess flow across the main relief valve at maximum pump pressure. Because the system never exceeds the correct flow, it does not have the consequential high flow induced pressure spikes resulting in cylinder and/or component failure. Hydraulic system flow is always available regardless of engine RPM, this allows pack on the fly and system operation capabilities without interruption. Unlike some over-speed control systems the operator never loses control of the hydraulic system. With constant controlled output flow available, cycle times, system efficiencies and productivity is maintained. The Flow Control/Unloader unit can be installed on new OEM equipment as well as retrofitted onto existing refuse equipment without major plumbing or system changes. Other more expensive pumps are not as tolerant of conditions that exist in the refuse market. Replacement and downtimes are minimized because of reliability, availability, and simplicity of design. Going Green is the only Sensible Choice. Versa-Pak Flow Control/Unloader System
