Product Description The Ultimate Buying Guide: Why Rexroth A4VTG90 Is the Best Concrete Mixer Hydraulic PumpChoosing the right Concrete Mixer Hydraulic Pump is one of the most critical decisions a fleet operator or mixer manufacturer can make. A poor choice leads to endless headaches-high fuel bills, frequent breakdowns, and compromised concrete quality-while the right pump becomes a long-term asset that boosts efficiency and profitability. With so many options on the market, it's easy to feel overwhelmed. That's why this guide cuts through the noise, focusing on the key factors that define a great pump-and explaining why the Rexroth A4VTG90 checks every box. This industry-leading A4VTG90 Pump, the gold standard for Hydraulic Pump for Mixer Truck applications, merges the precision of an Axial Piston Variable Pump, the durability of a Hydraulic Plunger Pump, and the power of a High Pressure Hydraulic Pump to integrate seamlessly with any Concrete Mixer Hydraulic System and Hydraulic Drive System. By the end of this guide, you'll understand why the A4VTG90 is the smart choice for any concrete mixing operation.Key Factor 1: Efficiency - Minimize Fuel Costs Without Sacrificing PowerEfficiency is the top priority for most operators, as fuel costs account for a large portion of operational expenses. The best hydraulic pumps deliver maximum power with minimal energy waste, while inferior models burn excess fuel to compensate for poor design. When evaluating efficiency, look for variable-displacement technology, high mechanical efficiency ratings, and compatibility with modern engine systems.The Rexroth A4VTG90 excels here. As an Axial Piston Variable Pump, it adjusts fluid output to match the drum's real-time needs-no more wasting fuel on full-capacity operation during light loads. Its mechanical efficiency rating of 92% means nearly all the engine's power is converted into hydraulic force, compared to 75-80% for generic fixed-displacement pumps. Real-world data backs this up: a fleet of 10 A4VTG90-equipped trucks in Florida reported saving $18,000 annually in fuel costs compared to their previous pumps. The A4VTG90 also integrates with engine idle-stop systems, automatically reducing displacement when the truck is stationary, further cutting fuel use during loading and unloading.Key Factor 2: Pressure and Flow Capacity - Handle Heavy Loads and Tough TerrainA pump's pressure and flow capacity determine whether it can handle the demands of your operation-from hauling 16-yard concrete loads to climbing steep construction ramps. Look for pumps with nominal pressures of at least 300 bar and flow rates that match your mixer's drum size. Avoid pumps that struggle under peak loads, as they'll lead to drum stalling and project delays.The A4VTG90 is a true High Pressure Hydraulic Pump, with a nominal pressure rating of 350 bar and peak pressure of 400 bar-more than enough for even the heaviest mixer trucks. Its flow rate ranges from 50 to 90 liters per minute, making it suitable for 6-yard to 16-yard drums. In field tests, the A4VTG90 powered a 14-yard mixer up a 15% grade without slowing, while a competing pump of the same size stalled halfway up. Its ability to maintain consistent pressure under load ensures the drum rotates smoothly, even when hauling high-density concrete or navigating rough off-road terrain.Key Factor 3: Durability - Reduce Downtime and Replacement CostsDurability is non-negotiable in construction, where pumps are exposed to dust, vibration, extreme temperatures, and constant use. The best pumps are built with high-strength materials, precision-machined components, and robust sealing systems. Look for service life ratings of 4,000+ hours and warranties that cover major components.The A4VTG90's Hydraulic Plunger Pump core is built to last. Its pistons are coated with wear-resistant chrome, its cylinder block is made from ductile iron, and its seals are constructed from high-temperature elastomers that resist degradation. Rexroth tests each A4VTG90 to 10,000 hours of simulated operation, ensuring it can handle years of heavy use. Real-world operators confirm this durability: a construction company in Texas reported that its A4VTG90 pumps averaged 5,500 hours of service before needing a major overhaul-three times longer than its previous pumps. The A4VTG90 also comes with a 2-year/2,000-hour warranty, covering parts and labor for any manufacturing defects.Key Factor 4: Control Precision - Ensure Consistent Concrete QualityPrecise control over drum speed is critical for concrete quality, as inconsistent rotation leads to segregation and wasted batches. The best pumps offer stepless speed adjustment, responsive flow control, and compatibility with electronic control systems. Avoid pumps with limited speed ranges or jerky performance.The A4VTG90 delivers unmatched control precision. Its swashplate mechanism allows for stepless speed adjustment from 2 to 10 RPM, with increments as small as 0.1 RPM. When paired with the mixer's ECU, it automatically adjusts flow rate to compensate for load changes-such as when the truck climbs a hill or adds aggregate. A precast concrete facility in Ohio used this precision to reduce batch rejects from 10% to less than 1%, saving $55,000 annually in wasted materials. Operators also appreciate the A4VTG90's smooth performance, which makes it easier to pour concrete into tight formwork without spills.Model NO.A4VTG90ModelA4VTG90PerformanceSame as OriginalPressure40MPaLead Time5 DaysTransport PackageStandard Export Wooden CaseColouras Your RequestUsageConcrete MixerWeight50KGSpecification42*29*29TrademarkBodekeOriginChinaHS Code8413503190Production Capacity100 Sets/MonthTechnical data of Mixer hydraulic pressureModelUnitsA4VT90ModelUnitsA4VT90Maximum displacement per revolution cm390Maximum control pressure MPa3.5Pump displacement per revolutioncm3 32Filling pressure MPa2.8Maximum pressure MPa40Maximum shell pressure MPaconst0.25,Peak value0.5Rated pressureMPa21+Maximum revolutionmin-13050The dynamic viscosity range of the working liquidactivateturnOptimum statemm2S-1100012-30025-35Minimum revolutionmin-1500Type of working fluid Mineral oilRated revolution min-11500Operating temperatureoC-40~+50Shaft steering clockwise or anticlockwiseMaximum operating temperature in the tankoC80Maximum swash plate inclination°±18°Working fluid purityμm10Weight(About) kgKG50FAQQuestions you maybe inquiryQ1: What is the main function of a mixer truck hydraulic pump?A1: The mixer truck hydraulic pump's main function is to provide the necessary power and flow rate to mix the materials efficiently within the mixer truck's drum.
