SP50.10.82D Stationary Concrete Pump — Small Diesel Trailer Pump

The SP50.10.82D is a diesel-powered stationary concrete pump engineered for horizontal concrete distribution and ground-level infrastructure projects. Mounted on a towable trailer chassis, it delivers a maximum theoretical output of 49 m³/h at pressures up to 10 MPa. The system integrates an 82 HP Cummins diesel engine, ensuring operational independence from site electrical grids. It utilizes an S-valve distribution system, a Kawasaki main oil pump, and an open-circuit hydraulic architecture with air cooling. With an operating weight of 4,509 kg and a compact footprint, the unit is optimized for rapid deployment across road construction, bridge engineering, and remote sites where larger boom pumps are geometrically or economically unfeasible. Manufactured to CE standards, the pump features a chrome-plated delivery cylinder and a dual-drive lubrication system for extended service life.

1. 49 m³/h Output — Delivers sustained concrete flow utilizing a Kawasaki main oil pump and an open-circuit hydraulic system.

Bridge Engineering: Pumps concrete efficiently to bridge decks, abutments, and foundational structures via fixed pipelines in spatially restricted environments.

Ground-Level Slab & Foundation Pours

Ground Foundations: Provides a highly maneuverable alternative to truck-mounted boom pumps for large-area ground slabs and footings.

Remote & Off-Grid Construction

Off-Grid Operations: The integrated Cummins diesel engine enables uninterrupted concrete placement in rural or undeveloped locations lacking reliable electrical grids.

FAQs

What are the primary applications of the SP50.10.82D?

The SP50.10.82D is a stationary diesel concrete pump utilized for horizontal infrastructure, including roads, bridges, light rail, and ground slabs. It delivers up to 49 m³/h at 10 MPa. For vertical pumping requirements in high-rise construction, the higher-pressure SP90 or SP100 models are specified.

Does the trailer-mounted configuration include an independent drive train?

No. The SP50.10.82D is mounted on a towable trailer chassis but lacks an independent road engine. It requires a towing vehicle for relocation. Once positioned, it pumps concrete through a stationary pipeline assembly.

What is the effective pumping range of this model?

Pumping distance is a function of pressure, mix design, and pipeline geometry (diameter and bends). The 10 MPa (100 bar) capacity is engineered for extended horizontal delivery and moderate elevations typical of bridge and roadwork. Precise reach calculations require evaluation of the specific pipeline layout.

Which concrete grades are compatible with the pumping system?

The S-valve pumping architecture processes concrete grades ranging from C15 to C70. Compatibility with the Φ180 mm concrete cylinder depends on the maximum aggregate size within the specified mix design.

How does the diesel configuration benefit site operations?

Equipped with an 82 HP air-cooled Cummins diesel engine, the pump operates entirely independent of local power grids. This autonomy is critical for rural infrastructure projects, bridge construction, and remote sites without established utilities.

What are the maintenance intervals for the wear components?

Wear part longevity correlates with pumping volume, pressure, and aggregate abrasiveness. The chrome-plated delivery cylinder exceeds a 100,000 m³ service life. The rigid-alloy cutting ring and spectacle plate are standard consumables requiring periodic inspection and replacement based on operational wear.

What equipment is included in the standard supply package?

The standard package comprises the trailer-mounted pump unit, integrating the Cummins engine, S-valve, hopper, and control system. Delivery pipelines, rubber hoses, spare-part kits, and commissioning services are customized and quoted based on specific project parameters.

Positioning within the A9 Stationary Pump Series

The SP50.10.82D serves as the compact, entry-level unit in the TRUEMAX A9 stationary concrete pump portfolio. Operating at 49 m³/h and 10 MPa, it is strictly configured for horizontal and low-elevation infrastructure. The series scales up to the SP90.18.253D (90 m³/h, 18 MPa) and the high-pressure SP100.23.360D (100 m³/h, 23 MPa) for mid-to-high-rise structural pouring. All models share the robust S-valve architecture and open hydraulic circuits, differentiated primarily by output capacity and maximum pressure ratings.

Concrete Supply Chain Integration

Stationary pumps function as the critical delivery mechanism in the concrete supply chain. Following transport via truck mixers, the SP50.10.82D propels the concrete through a customized steel and rubber pipeline to the exact pour location. For structural floor plates, the pump can interface directly with a concrete placing boom to optimize distribution efficiency.

Stationary vs. Truck-Mounted Pumping

Stationary trailer pumps offer significant operational advantages for ground-level, linear, or restricted-access projects. They require lower capital investment, possess a smaller footprint, and manage extensive horizontal pumping distances highly effectively. Conversely, truck-mounted boom pumps provide rapid deployment and vertical reach for open, elevated pours. The SP50.10.82D is the definitive choice for prolonged, ground-oriented infrastructure development.
