Putzmeister 430378 Thrust Ring – Axial Load Spacer

OEM-compatible Putzmeister 430378 Thrust Ring for TK40, TK50, TK60 and KATTKRETER pumps. Designed to absorb axial load and protect pump head drivetrain components.

Overview

The Putzmeister 430378 Thrust Ring is a precision-engineered sacrificial component designed to manage the intense axial loads generated in the pump head of TK40, TK50, TK60, KATTKRETER and related models. It ensures proper alignment and protects drivetrain components during high-pressure material delivery.

Applications

Compatible with:

• Putzmeister TK40

• Putzmeister TK50

• Putzmeister TK60

• KATTKRETER series

• P 715 / P 718 and similar mortar & conveying pumps

Used within the pump head assembly and coupling unit to ensure stable and pulse-free material flow.

Function

• Absorbs and distributes axial thrust load

• Maintains correct axial alignment between rotor and stator

• Protects bearings, gear motor, and coupling elements from overload

• Supports consistent dosing performance

Construction

Made from high-strength elastomer composite (Natural Rubber – NR) with internal steel reinforcement.
Provides vibration damping, high-pressure resistance, and long wear life.

Reference size: DN150 (≈150mm x 181mm x 29mm)

Key Benefits

• Protects expensive drivetrain components

• Ensures smooth, pulse-free material flow

• High durability with abrasive materials (mortar, screed, fine concrete)

• Supports mechanical efficiency and reduces heat generation
