City Pumps Construction

1. Stability
• Special hydraulic system with double pumps and double circuits: compared with single pump double circuits, the pumping system and distributing system are driven by two independent pumps that allow a more stable oil flow rate to the pumping unit.
• Intelligent control system: advanced technology, easy operation and high reliability electrical system.

2. High Efficiency
• Rapid concrete piston substitution: the pistons can be changed easily by a single operator without any special tools in 15 minutes. The hydraulic cylinder has an extra stroke to allow the piston to extend from the concrete cyli nder.

3. Energy Saving
• Super wear-resistant component: special steel alloy made spectacles wear plate and cutting ring plus high wear­ resistant cast steel material made mixing blade, ensuring a longer lifetime of weary spare parts.
• Hydraulic low/high pressure mode shifting: high/low pressure working mode is easily selected at the press of a button for variable heights of pumping.
