Putzmeister Agitator

Putzmeister Agitator Hydraulic Motor – Model No OMH-500 Supplier at Sonu Hose Pipe Overview:
Model No: OMH-500
Application: Concrete Pump Agitator Drive
OEM Part No: 238130001 (commonly associated)

Overview:
The OMH-500 hydraulic motor is a robust and high-torque motor engineered for use in Putzmeister concrete pumps, specifically as the agitator motor responsible for driving the mixing paddle within the hopper. Its primary function is to keep the concrete in constant motion, preventing segregation and ensuring a consistent, pumpable mixture.

Key Features:
🔧 High-Torque Performance:
Designed with a displacement of approximately 500 cc/rev, the OMH-500 delivers high torque at low speeds—ideal for heavy-duty mixing tasks within the concrete hopper.

🌀 Smooth Agitation Control:
Supports smooth and continuous rotation of the agitator paddles to maintain a homogenous concrete mix, even with coarse aggregates or varying slump levels.

🏗️ Heavy-Duty Construction:
Built with reinforced cast iron housing and precision-machined internal components for maximum durability under rugged construction site conditions.

🔩 Mounting & Fitment:
Standard 4-bolt SAE mounting flange and 35mm splined shaft, ensuring a direct replacement fit for OEM Putzmeister setups.

💧 Hydraulic Efficiency:
Designed for low leakage and high volumetric efficiency, contributing to better fuel economy and longer hydraulic component life.

Applications:
✅ Putzmeister Concrete Pumps – Agitator Motor (e.g., BSF, TK, P 718 models)

✅ Suitable for retrofitting or replacing damaged motors in hopper mixer drives

✅ Used in OEM and aftermarket repair of ready-mix and shotcrete pump systems

Benefits:
Prevents Concrete Hardening in Hopper
Continuous mixing action prevents concrete from settling or solidifying during pauses in pumping.

Reduces Maintenance Downtime
Durable design reduces the need for frequent servicing or premature replacement.

Improves Pump Efficiency
Ensures consistent flow of well-mixed concrete, protecting the main pumping cylinders.
