Schwing Adds Tier 4 Engine SP 500 Stationary Pump

Schwing is now providing their popular SP 500 stationary concrete pump with a Tier 4 compliant Caterpillar diesel engine. This is a response to government-mandated reductions in harmful exhaust gases from diesel-powered equipment. The California Air Resource Board (CARB) requires Tier 4 compliance for stationary pumps used on public and private projects. Other parts of the country are also requiring Tier 4 compliance depending on the locale and project. The CAT C3.4B diesel is rated at 74.5 hp while providing durability and fuel efficiency.

The SP 500 is a versatile machine with up to 45 cubic yards per hour output and 1100 psi maximum pressure on the material.

• The machine is capable of pumping grout, shotcrete or concrete.
• The twin-cylinder, all-hydraulic pump handles up to 1.5 inch aggregate with its six-inch diameter pumping cylinders operating through a 39-inch stroke.
• Sequencing the concrete to the pumping cylinders is the Rock Valve that enjoys proven reliability on Schwing’s largest concrete pumps.
• The Rock Valve cleans up faster using less water for high utilization on multiple projects in a day.
• Dual shifting cylinders provide positive valve actuation for smooth discharge.
• The open loop hydraulic system combines with the CAT engine to provide all-day economy from the 20-gallon fuel tank.
• Schwing SP models can be provided as skid, truck or trailer-mounted units.
• A convenient control panel on the side of the machine includes switches for on/off, forward/reverse and hopper agitator.
• Electric power is also available.
• A cable remote is standard with optional radio remote control.
