312D excavator hydraulic pump: a monologue of a "working pump"

2025-07-21

Hello everyone, I am 312D Hydraulic Pump, a "silent screw" who works on the construction site every day but has no social security and housing provident fund.

My nickname is "Hydraulic Man". You may not know who I am, but as long as 312D is still running, I will be giving love. Today I don't want to talk about performance, I just want to talk about the sadness and greatness of my "pump life"!

🛠 I am a hard worker, no, I am a heart that will work overtime!
Every day before dawn, the driver Lao Wang yawns and comes over, starts the car with a click -
I just dreamed that I retired, and was awakened directly.

"Come on, work for a day!" I thought to myself, and then gritted my teeth and pressed: "Raise the arm! Turn! Shovel the soil!"

What about that guy 312D? He was as comfortable in the cab as in the first-class cabin, listening to music while enjoying the air conditioning, and scolded me for being slow. I am slow? I am almost bleeding, brother!

💪 Without me, it dare not touch even a shovel of soil!
You see that 312D is majestic, but I am actually the one who supports it.

Its arms can be raised because of the hydraulic pressure I provide; its steering is flexible because of the oil circuit I direct. Without me, it would tremble even when turning around.

It relies on its face to make a living, and I rely on "pressure" to suffer. There is no way, I was born to bear pressure!

💦 Sweating profusely? No, I have a "calm Buff"
Others get hot when they work, but I am different:
I have a hydraulic cooling system, and the air cooling and oil cooling are clearly arranged, just like the "calm brother" on the construction site.

Last time when the temperature was 40℃, others stopped working, but I was still like a delicate working pump, with clear output and no slippage.

🧱 All the jokes on the construction site know: a good pump is one that is not broken!
Do you know how humble the hydraulic pump is? We don't have KPIs, the only goal is:
"No breakage, no leakage, no stopping!"

As long as I don't explode, the boss of the construction site won't even look at me. Only when it breaks down, will everyone watch: "Oh, this pump is not working anymore!"

Hey! Is this your attitude towards an old pump that "runs day and night, zero holidays"? !

🎉Written at the end: I am the soul pump of 312D and the most silent hero on the construction site
You may not pay attention to me every day, but as long as you drive 312D, I will press, press, press hard behind you!

🧡 So please, if you want to change the pump, change me! Don't buy those knockoffs that get upset every other day. I am durable, stable, and don't lose my temper. I can be called the "best teammate on the construction site"!

📦 Contact me and let your 312D "pump" move your heart and press all the way to the bottom!
