concrete mixer pump PV21
The PV21 and PV23 hydraulic pumps, manufactured by Sundstrand, are axial piston pumps designed for high-reliability operation in concrete mixer hydraulic systems. They can be used in both open and closed circuit systems, providing sufficient flow and pressure for heavy-duty concrete mixing. The PV21 has a displacement of 21 cm³ per revolution, while the PV23 displaces 23 cm³ per revolution. Maximum operating pressures reach 350 bar for PV21 and 360 bar for PV23, with maximum flows of 120 and 130 liters per minute, respectively. Each pump weighs approximately 55–60 kg, and the required input power at operational speed is around 100 kW.
The repair process begins with removing the pump from the hydraulic system and inspecting the housing and external connections for leaks or cracks. The cylinder block, pistons, swash plate, and drive shaft are measured using precision tools such as micrometers and gauges. Worn or damaged components are replaced to restore hydraulic performance and flow to factory specifications. All auxiliary components, including seals and O-rings, are also replaced to minimize leakage and prevent future failures.
After reassembly, the pump undergoes comprehensive performance testing. Operating pressure, output flow, input torque, and noise levels are mea

Mixer Drum with ZF and Italian Gearbox
Mixer drums with ZF and Italian gearboxes are industrial equipment designed for high-quality concrete production in construction projects. These drums are typically manufactured with capacities ranging from 3 to 12 cubic meters and made from alloy steel with 6 to 10 millimeter thickness. Rotation is powered by an industrial ZF or Italian gearbox with hardened gears. The driving motor, diesel or electric, delivers the required torque efficiently. The shaft and internal blades are made of high-strength steel with precise welding, ensuring uniform material mixing. Gear ratios and rotation speed are optimized for complete and homogeneous concrete blending.
Structurally, the mixer drum features a reinforced steel frame with anti-corrosion coating and industrial paint. ZF and Italian gearboxes operate with high-pressure lubrication and optimized cooling. The power transmission system includes shaft, coupling, and industrial bearings designed to handle radial and axial loads. The drum operates reliably within minus 20 to plus 50 degrees Celsius. Each unit undergoes functional testing, mixture uniformity inspection, and load testing prior to delivery to ensure durability and performance. These drums are suitable for high-volume construction, civil, and industrial projects.

Truck Mixer
A truck mixer is a concrete transport and mixing unit mounted on a truck chassis with a capacity ranging from 6 to 14 cubic meters. The mixing drum is manufactured from wear resistant steel with thickness between 4 and 6 millimeters. The drum inclination angle is typically set between 12 and 15 degrees relative to horizontal to optimize gravity discharge. Rotational speed is 8 to 14 rpm during mixing and 2 to 4 rpm during transit. The drive system is usually hydraulic, using a piston pump and hydraulic motor operating at 250 to 350 bar. Effective drum filling ratio is approximately 85 percent of nominal capacity.
The chassis and subframe are fabricated from structural steel with minimum yield strength of 355 megapascals. Dual purpose internal blades perform both mixing and reverse discharge functions. A water tank with capacity of 400 to 800 liters is installed to adjust concrete slump. Truck engine power is typically selected between 280 and 450 horsepower. Quality control includes drum balance testing, hydraulic leakage inspection, and internal lining thickness verification. Service life of the drum under standard conditions exceeds 100000 loading cycles.
