1. What rate and pressure do you need?
Pick the plunger by discharge pressure first, then check that its maximum rate covers your dose.
| Plunger size | Max rate per head | Max pressure |
|---|---|---|
| 1/4" | 17 GPD | 6,000 PSI |
| 3/8" | 37.5 GPD | 3,000 PSI |
| 1/2" | 70 GPD | 1,250 PSI |
| 1-1/2" | 600 GPD | 300 PSI |
2. What power is available?
All our pumps run on 12/24 VDC solar or 120 VAC. For remote wells, choose a pump with efficient brushless motors and plan solar around its draw.
3. Is the location classified?
Oilfield sites are often Class 1 Division 2. Our pumps are C1D2 certified.
4. Will the materials survive your chemical?
Check wetted materials against your chemical: 316 stainless steel, solid ceramic plungers, PTFE/FFKM energized seals. Always confirm compatibility with your specific product, concentration, and safety data sheet. Our team will review your chemical and conditions before you order.
5. How much control and visibility do you need?
