Trucks and heavy equipment Heavy Equipment 🔧 Comprehensive Hydraulic Circuit Maintenance – Cifa K56C Concrete Pump 🔧 Is your concrete pump overheating? Or are the boom connections unresponsive? ✋ The problem is often deeper than you think... and it might start with a non-original filter! 📌 Fault Diagnosis: The Cifa K56C pump arrived with issues in boom connections #1 and #5. After a thorough engineering inspection, the root cause was identified as: 🔸 Use of non-original filters, which led to impurities in the hydraulic circuit. 🔸 Power failure to the ED72 valve (Negative Characteristic Control) for the S-valve pump, causing the pump to remain at maximum angle permanently under charge pressure. 🔸 This resulted in a massive increase in circuit temperature. 🔸 The consequence: failure of the non-original filters and transfer of particles to the piston valves, causing them to malfunction. ✅ Work Performed: ✔ Repaired issues with boom connections #1 and #5, restoring them to efficient operation. ✔ Repaired the cylinder for boom connection #4. ✔ Complete periodic maintenance: Oil change + original filters. ✔ Installed pressure gauges on: • Main Pumping Circuit A4VG 175EP series 40 x2 • Charge Pump Circuit • Changeover Circuit A10VO 28 ED72 • Boom Circuit A7VO 55 LRDS This allows for regular monitoring of the pump's condition and early detection of any faults before they become costly breakdowns 📊 Advice from the Engineers: A cheap filter can cost you the entire circuit repair. Always use original filters and oils, and install pressure gauges to monitor your pumping equipment. 🏢 Global Hydraulic Power Specialists in the maintenance and repair of hydraulic systems for concrete and heavy equipment 🌐 www.globalhydraulicpower.com 📞 0559015147 | 0599635314 📲 WhatsApp: 📍 Riyadh – Al Sulay – Exit 17 #مضخة_خرسانة #سيفا #Cifa #K56C #صيانة_هيدروليك #هيدروليك #الرياض #السعودية #معدات_ثقيلة #مضخات_خرسانة #جلوبال_هيدروليك_باور #حراج #صيانة_معدات
