As part of EMAC, PumpMac provides abundant premium pump-driven power pack options, WPT PTO, Advance gearbox and pump head, as well as customized water pump set. We also have a set of NFPA20 standard engine power pack accessories including air intake shut-off valve, DC contactor, engine control panel, jacket water heater etc. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

1.Leading design and excellent manufacturing technology make the engine more reliable and durable, suitable for high-strength, heavy-duty work under severe working conditions.
2.Advanced four-valve structure, greater power, more thorough air combustion, higher low-speed torque and higher operating efficiency.
3.Forced cooling articulated pistons are used to withstand higher mechanical and thermal loads, comparable to the strength of heavy-duty engines.
4.Enhanced cylinder design, significantly reducing noise and vibration.
5.Powerful driving air-to-air cooling and turbocharging technology, better engine power.
6.The use of central fuel injector, the combustion chamber is symmetrical, the mixing in the cylinder is more uniform, the combustion is more thorough, and the emission is lower.
7.The size of the engine is smaller than that of the same type of engine, the maintenance space is large, and the maintenance is faster.
8.Strong interchangeability, more convenient equipment upgrades.
