SP90.18.253D Stationary Concrete Pump — Diesel Pump for Mid- to High-Rise Buildings

The SP90.18.253D is a mid-range stationary concrete pump specifically designed for vertical concrete distribution in mid- to high-rise building construction. Mounted on a towable trailer chassis, it integrates a 253 HP air-cooled Deutz diesel engine, providing operational independence from site electrical grids. The pumping system utilizes a Rexroth main oil pump and an S-valve distribution mechanism, delivering a maximum theoretical output of 90 m³/h and achieving concrete pressures up to 18 MPa. This high-pressure capability allows it to effectively push concrete up vertical riser pipelines. The unit features a Φ200 × 1800 mm chrome-plated concrete cylinder, an open-circuit hydraulic system with a compact integration block, and an energy-saving power-matching algorithm that improves fuel efficiency. Engineered to CE and ISO 9001:2015 standards, the SP90.18.253D offers robust, continuous pumping for demanding structural pours.

Dimensions & Working Range

The dimensional drawing illustrates the geometry of the towable trailer unit (7,130 × 2,065 × 2,680 mm), facilitating logistical planning for transport and site positioning. Weighing 7,200 kg, the SP90.18.253D is typically stationed at ground level, interfacing with a vertical riser pipeline to supply concrete to elevated floor plates. Installation planning must account for the pump's footprint, dump-truck access to the 0.6 m³ hopper, and the routing of the high-pressure pipeline.

Applications

The SP90.18.253D is engineered for vertical concrete distribution, providing the necessary pressure and volume for mid-to-high-rise structural pouring.

Mid- and High-Rise Construction

High-Rise Construction: Pumps concrete vertically through fixed riser pipelines to service elevated floor plates, shear walls, and core structures.

Multi-Storey Commercial Developments

Repetitive Floor Pours: Offers a highly efficient, stationary alternative to boom pumps for multi-storey residential and commercial developments.

Structural Cores and Vertical Pours

Structural Elements: The 90 m³/h capacity and robust S-valve efficiently handle complex structural mixes (C15–C70) required for columns and abutments.

Off-Grid Pumping Operations

Early-Stage Projects: The independent Deutz diesel engine provides reliable pumping capabilities on developing sites lacking established electrical grids.

FAQs

What differentiates the SP90.18.253D from the SP50 and SP100 models?

The models are differentiated by output and pressure. The SP50.10.82D (49 m³/h, 10 MPa) is configured for horizontal and ground-level work. The SP90.18.253D (90 m³/h, 18 MPa) serves mid-to-high-rise construction. The SP100.23.360D (100 m³/h, 23 MPa) is engineered for extreme high-rise applications. All utilize an S-valve distribution system.

Is the unit self-propelled or trailer-mounted?

The SP90.18.253D is a stationary concrete pump mounted on a towable trailer chassis. It lacks an independent road engine and must be towed by a tractor unit. Once positioned at the site, it connects to a fixed pipeline system.

What is the maximum vertical pumping reach of the SP90.18.253D?

Pumping reach is contingent upon concrete pressure, mix design, and pipeline geometry (diameter and bends). As a general engineering metric, vertical concrete elevation requires approximately 1 bar of pressure per 10 meters, excluding friction losses. At 18 MPa (180 bar), this model is optimized for mid-to-high-rise structures. Precise reach calculations require evaluation of the specific pipeline layout.

How does the high/low-pressure switching function optimize operations?

The system allows operators to mechanically adjust the hydraulic displacement. High-pressure mode maximizes vertical reach for tall structures, while low-pressure mode increases volumetric output (up to 90 m³/h) for horizontal or lower-elevation pours where maximum pressure is unnecessary.

What are the advantages of the Deutz diesel engine configuration?

The 253 HP Deutz engine ensures total operational autonomy, eliminating reliance on site electrical grids. Furthermore, it incorporates a power-matching algorithm that optimizes fuel consumption by up to 10% and improves pumping efficiency.

What is the expected service life of the primary wear components?

Component longevity depends heavily on concrete abrasiveness, pumping pressure, and volume. The chrome-plated Φ200 mm delivery cylinders are rated for over 100,000 m³. The rigid-alloy cutting ring and spectacle plate are standard consumables requiring periodic inspection and replacement based on operational wear.

What is included in the standard equipment supply?

Standard supply comprises the trailer-mounted pump unit, integrating the Deutz engine, Rexroth main oil pump, S-valve, and intelligent control system. Auxiliary equipment, including steel pipelines, rubber hoses, transport homologation, and commissioning services, are customized and quoted based on project requirements.

Positioning within the TRUEMAX A9 Series

The SP90.18.253D occupies the mid-range tier of the TRUEMAX A9 stationary concrete pump portfolio. It bridges the gap between the compact SP50 series (designed for civil and ground-level infrastructure) and the ultra-high-pressure SP100 series (engineered for extreme vertical reach). This model provides the optimal balance of volume (90 m³/h) and pressure (18 MPa) for the majority of multi-storey commercial and residential developments.

Vertical Distribution Logistics

In high-rise construction, the stationary pump acts as the primary propulsion unit. Positioned at ground level, the SP90.18.253D receives concrete from truck mixers and drives it vertically through a rigid steel riser pipe. At the active floor level, the pipeline typically interfaces with a concrete placing boom, allowing for precise, mechanized distribution of the material across expansive floor plates.

Stationary vs. Boom Pump Deployment

While truck-mounted boom pumps offer rapid setup for lower-elevation or highly mobile pours, stationary pumps like the SP90.18.253D are economically superior for high-rise projects requiring repetitive, high-volume floor pours. Once the vertical pipeline and placing boom are established, the stationary pump provides continuous, high-pressure delivery without the spatial or height limitations inherent to boom trucks.
