Oil/Gas
Pumps are used in the oil and gas industry across the globe to handle the transfer of oil and gas, provide fire protection, supply hydrostatic pressure to blow-off preventers, and perform trenchless underground boring.
A variety of high flow and high-pressure pumps are available depending on the application. Our pumps’ long life and quality materials are essential features to these 24/7 tasks.
When the Stakes Are High, “Good Enough” Isn’t Enough
You never walk into an oilfield thinking “today, we’ll settle for average.” In oil & gas, every pump ties directly to safety, uptime, and sometimes lives. Whether it’s keeping fire protection systems online, pressurizing blow-off preventers, pushing fluids across remote pipelines, or boring under cities, your equipment has to work not when it’s easy—but when it’s brutal.
That’s where General Pump comes in. We don’t build pumps for spec sheets. We build pumps that survive sweat, sand, salt, pressure, extreme temperature—and long hours.
Built for continuous duty in harsh conditions
Oil and gas operations push pumps harder than almost any other industry. Fluids can be abrasive or corrosive, duty cycles are long, and the pressure and flow requirements swing from steady transfer to critical, safety-related surge. General Pump supplies high-flow, high-pressure pump solutions used for oil and gas transfer, fire protection, hydrostatic pressure for blow-off preventers, and trenchless underground boring—applications that run day and night and reward long-life designs and quality materials.
What to expect from General Pump in Oil & Gas
- Application coverage: Solutions for transfer, fire protection, hydrostatic testing (including BOP support), and trenchless boring.
- Performance headroom: Cataloged options spanning very high pressures (to 22,000 PSI) and high flows (to 700 GPM), so engineers can size correctly without operating on the edge.
- Proven pedigree: General Pump has specialized in plunger pumps since 1982 and serves oil & gas among other heavy industries.
- Serviceability & care: Clear lubrication schedules and technical literature (Installation, Troubleshooting, Unloader Operation, SDS) make maintenance predictable in the field.
Where these pumps work best
Fluid transfer
Move crude, produced water, or mixed fluids with reliable flow and materials matched to the medium (e.g., corrosion-resistant manifolds, hardened wear parts, and seal options for chemical exposure).
Fire protection
High-readiness configurations that deliver pressure immediately when safety systems are actuated—designed to sit idle without degrading and then perform on demand.
Hydrostatic testing (including BOP support)
Maintain precise, high pressure for leak-tightness and integrity checks in pipelines, vessels, and well control systems. In regulated contexts, test pressure is typically a defined multiple of normal operating pressure to validate integrity (e.g., pipeline tests at ≥125% MOP for set durations).
Trenchless boring / HDD
Handle abrasive slurry and frequent cycling with pump heads and sealing systems designed for wear resistance and easy field service.
Design choices that matter in oil & gas
- Flow & pressure sizing
Engineers should size with margin on both axes (GPM/PSI) to avoid cavitation, overheating, and premature wear. General Pump’s range up to 700 GPM and 22,000 PSI helps you specify for worst-case conditions without over-stressing the unit. - Materials & sealing
For sour gas, saltwater, or solvent exposure, choose corrosion-resistant alloys and compatible seals (e.g., PTFE/Viton). Correct materials at the outset reduce leakage and extend service life in aggressive media (industry maintenance literature consistently pinpoints corrosion and seal incompatibility as primary failure drivers). - Inlet conditions & filtration
Many field failures trace back to suction-side issues: starved inlets, undersized strainers, or clogged filters that drop NPSH and trigger cavitation. Good inlet design and filtration dramatically reduce damage to valves and seats. - Lubrication discipline
Follow the break-in and routine oil change schedule (initial change ~50 hours; then every 3 months or 500 hours, model-dependent). Using the specified General Pump oil is part of the warranty and a proven way to avoid early bearing/seal failures.
Oil & Gas Pumps FAQs
1) What pressure and flow ranges are available for oil & gas work?
General Pump catalogs include models up to 22,000 PSI and 700 GPM, covering transfer through to high-pressure integrity tests.
2) Do you support hydrostatic testing for BOPs and pipelines?
Yes. Solutions are used to supply hydrostatic pressure for well control and pipeline integrity testing. Regulatory guidance typically requires testing above normal operating pressure (e.g., pipelines ≥125% MOP for specified durations).
3) What maintenance schedule should our crews follow?
After break-in (~50 hours), change pump oil every 3 months or 500 hours with the specified General Pump oil (Series 100 / model-specific). Check levels daily in heavy service.
4) How do we avoid cavitation and early valve/seal wear?
Provide adequate NPSH at the inlet, size/maintain strainers properly, minimize suction-side restrictions, and avoid long dry-run conditions; these are foundational best practices.
5) Which materials should we choose for sour or saline environments?
Select corrosion-resistant manifolds and compatible seals (e.g., PTFE/Viton) for H₂S or saltwater exposure; this materially improves service life and leak resistance.
6) Do you publish technical documentation and service support?
Yes—General Pump maintains oil recommendations, SDS, installation/service manuals, troubleshooting guides, unloader operation, and service videos for technicians.
7) Can your pumps sit in “ready” state for fire systems and still start cleanly?
They’re built for reliability in safety-critical roles; pair with proper accessories (relief valves, gauges, inlet filtration) and follow the maintenance schedule for assured readiness.
8) What if we’re unsure about sizing or materials?
Provide your duty cycle, fluid properties, and target GPM/PSI. General Pump’s application support references catalog limits and material options to match the job.
