29570747 housing assembly-pump Allison spare parts

As a core pump body component compatible with Allison original equipment manufacturer (OEM) specifications, the Allison 29570747 pump housing assembly is the core of the pump system’s outer shell. It bears the installation and protection of key components such as internal impellers, bushings, and seals. It is designed specifically for the harsh operating conditions of Allison series hydraulic pumps and gear pumps, and precisely matches the pump body requirements of Allison gearboxes, heavy engineering machinery equipment, and special vehicles. It is a key consumable material that ensures pump body sealing, pressure stability, and efficient medium delivery.
This product strictly adheres to Allison’s original manufacturing standards, using HT250 high-strength gray cast iron. This material possesses excellent casting performance, mechanical strength, and wear and corrosion resistance. It has good fluidity and low shrinkage, effectively withstanding the high-pressure impact and media corrosion during pump operation, making it suitable for the high-temperature and high-pressure working environment of pump systems. The product undergoes multiple processes including sand precision casting, aging heat treatment, and precision machining. Its internal flow channels are specially optimized to reduce media flow resistance and improve pump delivery efficiency. It also boasts core advantages such as excellent sealing performance, high-pressure and impact resistance, resistance to deformation, and long service life. It effectively encapsulates and protects the internal structure, withstands the pressure difference between the pump body and pipeline, prevents media leakage, avoids pump system failures caused by pump casing damage or deformation, reduces downtime losses, extends the overall service life of the pump system, and lowers subsequent maintenance costs. It is widely used in mainstream Allison equipment applications such as agriculture, construction, mining, fire emergency response, and oil and gas, adapting to various harsh operating environments. Balancing practicality and economy, it is a core component for Allison pump system maintenance.

Core technical parameters:

– Product Model: Allison 29570747
– Product Type: Pump Housing Assembly
– Core material: HT250 high-strength gray cast iron
– Material characteristics: Tensile strength ≥250MPa, hardness ≥180 (5/250/30)HBS, impact toughness ≥15J/cm², density approximately 7.2g/cm³, excellent high-temperature resistance, can withstand working temperatures from -40℃ to +180℃, corrosion resistant, impact resistant, and not prone to cracking or deformation.
– Casting process: Sand precision casting + aging heat treatment (holding at 600±20℃ for 8~10 hours, followed by furnace cooling), resulting in high dimensional accuracy and freedom from defects such as sand holes, porosity, and cracks. This effectively improves the structural stability and service life of the product and avoids material concentration shrinkage cavities and gas absorption tendencies.
– Surface treatment: The inner and outer surfaces are treated with anti-rust paint, with a film thickness of 0.03~0.05mm. The paint has strong adhesion and can effectively resist moisture and media corrosion, extending the anti-rust life. The internal flow channels are precision polished, with a surface roughness Ra≤0.8μm.
– Core dimensions: Pump casing outer diameter 168mm, length 215mm, inlet/outlet diameter 50mm, mounting hole spacing 80mm, mounting hole diameter 12mm, inner cavity diameter 105mm. Conforms to the original factory mounting dimensions of Allison series pumps, ensuring a precise fit without modification.
– Compatible Models: Allison series hydraulic pumps, gear pumps, and transmission pump bodies; heavy-duty construction machinery and special vehicles (including mining dump trucks, agricultural machinery, fire emergency vehicles, oil and gas exploration equipment, etc.); precisely matches the original factory mounting positions and can be directly replaced.

The Allison 29570747 pump housing assembly, with its original equipment manufacturer (OEM) compatibility, superior high-pressure and shock resistance, and excellent sealing, has become the preferred consumable for maintaining Allison pump systems. Whether for personal equipment maintenance, bulk corporate purchases, or engineering maintenance support, it meets diverse needs. The product is easy to install, requiring no specialized tools, and can directly replace the original pump housing assembly. It effectively solves common faults such as pump housing damage, leakage, and deformation, reducing equipment downtime due to pump housing failure, lowering maintenance costs, and improving equipment operating efficiency.
