A Complete Selection of Material for High Pressure Cleaner Pump Heads
A Complete Selection of Material for High Pressure Cleaner Pump Heads
I. Contrast of Mainstream Pump Head Material
1. All Copper Pump Head (brass / copper alloy)
Advantage
Corrosion resistant, oxidant resistant and not prone to rust
Good thermal conductivity and strong seal stability
High pressure resistance, long service life, commercial / industrial preferred
shortcoming
High cost and heavy weight
Suitable for: car washes, construction sites, commercial high pressure machines, crankshaft pump owners, long-term high frequency use
2. Aluminum pump head
Advantage
Lightweight, low cost, and high value for money
Standard for home models
shortcoming
Poor corrosion resistance, easy oxidation, skin peeling, and water leakage
Not resistant to high pressure, acid and alkaline cleaning agents
Suitable: Small domestic cleaning machine, occasional use, low pressure model
3. Plastic Pump Heads (Engineering Plastic / Nylon)
Advantage
Extremely light and cheapest
Protect against minor corrosion
shortcoming
Very poor pressure resistance, easy to age and crack, short life
Suitable: Mini handheld car wash machine, a low-cost entry model, temporary occasional use
4. Stainless steel pump head
Advantage
Strongest corrosion resistance, resistance to acid and alkali, resistance of seawater, resistance against sewage
shortcoming
High processing difficulty, high cost, and self-gravity
Suitable: Chemical, farming, wastewater environment, special corrosion conditions
5. Ceramic cylinder + copper pump (high-end configuration)
Advantage
Resistant to wear and tear, almost non-wear, and life is more than 3 times that of ordinary pumps
High pressure is stable and does not leak easily
Suitable: High pressure shaft pump, industrial grade cleaning machine, special pump for washing floors
II. How to select according to the use scenario
Home's suitable choice for occasional car wash: aluminum pump head is enough and saves money
Car Wash / Store Choose Every Day: Whole Copper Pump Head + Ceramic Pillars durable and less maintenance
Worksites, dirt, long-term high loads choose: fully copper crankshaft pump pump head
Farming, chemicals, and foam-based alkaline cleaning options: stainless steel / all-copper preservative
Mini portable radios are basically plastic / simple aluminum pumps, don't have to worry
III. Key points for avoiding a pit
At the same pressure, all copper > aluminum alloy > plastic
Never choose an aluminum pump for long-term business, when water leaks in half a year and the pump is not worth it.
The high pressure shaft pump must have a full copper pump head + a ceramic jack, and cannot use aluminum
Use foam pots, strong cleaning agent conditions, prefer all copper / stainless steel, aluminum pumps are prone to corrosion and damage
