The SP 1400 - “A SCHWING solution for high delivery volume with low concrete pressure , low delivery volume with high concrete pressures & high fuel efficiency in the compact-class with 48 kW engine power. Therefore the SP 1400 is designed with a whole row of excellent features in usual SCHWING quality. As on all SCHWING concrete pumps , the SP 1400 has an output-governed hydraulic pump that ensures that the prime mover is never over loaded, the automatic governor splits available engine output optimally into oil flow and oil pressure and allows the concrete pump to run at the best possible output level . At the same time, the manual de-stroker valve can be used to set the pump to a required fine-tuning to set stroke rate and output independent of the automatic governor.
The open circuit, combined with the SCHWING designed “Hi-Flow” spool block ensures minimum heat generation in the hydraulics, therefore negligible output losses and minimum stress for the hydraulic components.
During shor the main control spool is shifted to “idle circuit” so that all of the oil coming from breaks in pumpin hydraulic pump flows pressur the back to the tank, thereby making a fur ther contribution towards keeping oil temperatures low. On SCHWING pumps, there is no feed pump that runs on continually and turns valuable energy into wasteful heat.
The hydraulic control system is integrated within the drive. The compact Control block & minimal hydraulic lines makes the equipment Reliable & durable.
Direct high- torque driven on to the agitator shaft as well as robust design of all hydraulic components in conjunction with constant flow micro-filtering of the hydraulicoile nsure operational reliability and a long service life.
A central bank of grease nipples supplies grease to all of the lube points on agitator and rock valve.
Compact design individual switching circuit ensures quick operation of rock valve.
The SP 1400 comes complete with a 10m cable remote control as a standard feature.
Normal Rock or RL-Rock? Among concrete valves, the normal rock valve is the classic known all over the world. For more than 20 years, it has been the paragon of power and reliability. It is patented in practically all industrialized countries it offers exemplary pumping characteristics, wearing proper ties and operational safety.
RL– Rock Valve, is a new generation Rock Valve, Engineered by SCHWING R&D after extensive study of behaviour of tough concrete in various developing countries. This rugged, reliable Rock Valve is highly suited for stiff, difficult mixes of concrete and ideal for use in combination with the long-stroke pumping unit. An option that can be recommended is the hard-facing layer for extremely long service life.

The motor (Diesel or Electric) drives the axial piston pump via a flexible coupling. Due to automatic output adjustment optimum utilization of the motor power, resulting in low energy consumption at differing pumping condition. Additionally the concrete flow can be manually adjusted. The pump operates in a proven open circuit.
The maximum placing output and the pressure are determined by the construction sites. Between these two values automatic adjustment by the governor occurs maintaining a constant output depending on the power available from the installed drive motor.
The por table concrete pumps are assembled in the unit construction system.
The main assembly groups are: Frame, Power unit, Concrete pump kit, Control block, Hydraulic tank and Hopper with agitator.
The frame, in compact execution, is constructed from standard vehicle profiles. The pump is mounted on heavy duty single axle chassis with draw bar, pneumatic tyres and for travelling on construction sites at up to 25 km/hr.
The fully hydraulic control system is integrated within the drive. The compact control block and minimal hydraulic lines makes the equipment reliable and durable. The differential cylinder has trouble free piston rings and automatic constant stroke maintenance. Both gate valves change independently so that even when full change over is prevented by foreign material or similar obstructions in the concrete, the pump continues to operate without problems. All components are especially developed and manufactured to withstand the rough treatment on construction sites.
Ideal flow conditions in the control housing resulting in superior placing proper ties also incase of concrete low on sand and fines, stiff consistence or crushed aggregates. Simple tilting of the output pipes enables easy control and cleaning of the concrete conveying path and the gate valve par ts.
Pumpable concrete, within any consistency range down to a water cement ratio of 0.4. Even concrete with aggregate grading up to
40mm can be conveyed trouble free with the concrete pump through a 125mm diameter pipe line.
The two flat gate valves working independently have been especially developed for pumping concrete. Their working system with automatic adjustment permits trouble free pumping even with badly worn parts.
