Details

Product Name: Helical Spring / Compression Spring (Part No. CP020034/255)

Description:
This component is a helical compression spring (specifically listed as a "helical spring" or "compression spring"), specifically designed for BFT waterjet intensifier pumps . It is a precision coiled component manufactured from high-grade stainless steel , which provides resistance to corrosion and maintains spring tension under extreme pressure cycling.

Engineered for reliability in ultra-high pressure waterjet environments, this spring is a critical component used in the intensifier assembly. According to parts lists for the CP022001/2 Intensifier, this spring is installed in the hydraulic control section of the pump and is listed as Item 21 .

Applications:

Used as a component in the intensifier assembly of BFT waterjet cutting systems (Part of CP022001/2) .
Serves as a mechanical element, primarily to ensure the precise function of the piston displacement sensor .
Compatible with BFT intensifiers, as well as systems from BHDT, Maximator Jet, STM, and Intermac Primus .
Rated for ultra-high pressure operation up to 4,137 bar (approximately 60,000 PSI) .

Features:

Stainless Steel Construction: Manufactured from high-grade stainless steel for corrosion resistance and long-term fatigue life .
Precision Coiled Design: Manufactured to exact tolerances to ensure consistent spring force and reliable operation under high cycle rates.
Critical Positioning Function: Directly responsible for the precise operation of the piston position sensor, affecting pump shift timing .
Lightweight: Weight is approximately 0.001 kg (1 gram), making it easy to handle during maintenance .
Cross-Reference Compatibility: Interchangeable with part numbers MJ0040084, 4100794, and 106777 .

Maintenance:

Failure Diagnosis: A symptom of a broken or fatigued spring is often erratic intensifier shifting or the pump failing to change direction properly, as the sensor cannot detect the piston position accurately .
Inspection: When the intensifier is disassembled for maintenance, inspect the spring for signs of permanent deformation (shortening), cracking, or corrosion. Compare its free length to manufacturer specifications.
Replacement: This is a high-cycle wear component. It should be replaced during major pump overhauls or immediately if the intensifier exhibits erratic shifting behavior.
Full Depressurization (Critical): Before any maintenance, place the main electrical disconnect in the OFF position, bleed down all high-pressure lines, and follow lockout/tagout procedures.
Clean Installation: Ensure the spring cavity is clean and free of debris before inserting the new spring.
Torque Compliance: When reassembling the intensifier, tighten the relevant retaining components to the torque values specified in the equipment service manual.
