PDP4 ISO 12.5

Product catalog summary

Specifications:
The document outlines the specifications for the PDP4 hydraulic couplings. Key features include interchangeability with Stucchi DP4, flat face occlusion, and a lever locking mechanism with a safety device. The materials used are steel and aluminum, with finishes such as Zn-Fe (Cr III), Zn-Ni, and cataphoresis. Threads available include BSP, NPT, SAE, and metric options. Standard seals are NBR and PU, with optional seals available in FKM and EPDM. The working temperature range is -25°C to +100°C, and the working pressure is 350 bar. Connection under residual pressure is allowed on the male side only.

Technical Data:
The nominal size is 20 mm with a maximum working pressure of 12.5 MPa. The rated flow is 10.7 l/min, with a maximum flow rate of 35 l/min. The minimum burst pressure is 90 MPa for male, female, and coupled configurations. Fluid spillage is minimal at 0.010 cc.

Dimensions and Threads:
The document provides detailed dimensions and thread specifications for both fixed and mobile parts of the PDP4 couplings. Various thread standards are listed, including BSP, NPT, and UNF, with corresponding part codes and weights.

Spare Parts:
A comprehensive list of spare parts for both fixed and mobile plates is provided, including part numbers and weights. Specific spare parts for seals and couplings are also detailed.

Accessories:
Accessories such as plate caps and docking stations are listed with part numbers and weights, providing additional options for customization and maintenance.
