Putzmeister 444384 Spectacle Wear Plate – 160×170 S-Valve Plate

OEM-compatible Putzmeister 444384 Spectacle Wear Plate for TK70 and 160×170 pumping systems. High-abrasion wear plate engineered for S-Valve transfer sealing.

Overview

The Putzmeister 444384 Spectacle Wear Plate is one of the most essential wear components in Putzmeister concrete and mortar pumps. Its “spectacle” design enables the S-Valve to alternate material flow between cylinders and the delivery line, ensuring consistent, high-pressure pumping performance.

Built to withstand extreme friction and abrasion, this plate is engineered for demanding environments and continuous-duty concrete pumping.

Applications

Compatible with:

• Putzmeister TK Series (e.g., TK70)

• Trailer pumps using the 160 × 170 mm pumping system

• Mortar and fine concrete pumping equipment with spectacle-plate S-Valve transfer systems

Function

• Creates a precise seal between cylinders and the cutting ring

• Prevents backflow and pressure loss

• Ensures efficient material transfer through the S-Valve

• Protects the hopper shell and S-Valve from accelerated wear

Construction

• High-strength steel base

• Critical wear surfaces reinforced with Tungsten Carbide Alloy or DURO22 hardfacing

• Designed to exceed 30,000 m³ in service life under proper operating conditions

Reference size: 160 × 170 mm spectacle opening

Key Benefits

• Maximum Abrasion Resistance: Tungsten Carbide/DURO22 options provide extended life under abrasive concrete.

• Optimal Sealing: Maintains the essential seal at the transfer point for peak pump efficiency.

• Critical Wear Part: Acts as a sacrificial component to protect expensive structural parts.

• Precision Engineering: Ensures perfect alignment with the cutting ring for stable performance.
