API 676 Multiphase & Rotary Pumping Solutions
We package multiphase twin screw rotary pumps for pumping oil, gas, water, gas void fraction, and upstream boosting. By integrating 3P Prinz’s world-class rotary positive displacement technology with Calder’s decades of specialized engineering experience, we deliver robust, custom-engineered process and utility packages tailored to the demanding requirements of onshore and offshore energy operations.
Strict API 676 Compliance
The 3P Prinz portfolio features advanced Twin Screw and Hollow Rotary Disk pumps engineered in full compliance with the API 676 standard. Built for heavy-duty, continuous operation in harsh industrial environments, these pumps deliver:
- A minimum 20-year design life with exceptional reliability and extended maintenance intervals.
- Pressure-containing wetted parts crafted from cast steel, stainless steel, or specialized high-grade alloys.
- Rigid, heavy-duty baseplates and robust bearing assemblies designed to withstand severe continuous-duty cycles.
Multiphase Twin Screw Pumps: Streamlining Complex Production
A core highlight of our 3P Prinz integration capability is their specialized Multiphase Twin Screw Pump technology.
In oil and gas recovery, wellheads frequently produce an unseparated, highly volatile mixture of natural gas, heavy crude oil, and produced water. Historically, managing this fluid stream required a complex array of surface infrastructure – including test separators, gas scrubbers, downstream compressors, and separate liquid pumps.
3P Prinz multiphase technology optimizes this entire architecture:
- Simultaneous Gas and Liquid Boosting: These pumps ingest and compress fluctuating ratios of gas and liquid phases concurrently within a single, compact unit.
- High Gas Void Fraction (GVF) Handling: Engineered to manage sudden gas slugging and high GVF conditions safely without vapor lock, surging, or mechanical damage.
- Reduced Footprint and CAPEX: Direct boosting of untreated wellstream fluids eliminates intermediate separation stages, significantly lowering topside platform weight and capital expenditure.
- Enhanced Field Economics: Stabilizes well flow and maximizes recovery over the declining lifecycle of a reservoir.
Engineered Integration into Calder Process Packages
At Calder, we do not just supply standalone equipment; we engineer, manufacture, and test complete, turnkey process packages built to exact client specifications. We seamlessly integrate API 676 rotary and multiphase pumps into fully certified skids.
Our comprehensive package integration includes:
- Custom Skid & Structural Design: Fabrication of rigid baseplates and modular skids engineered to meet API standards and strict DNV offshore requirements.
- Hazardous Area & Environmental Certification: Full compliance with NORSOK, ATEX, IECEx, and CSA standards, alongside optional custom enclosures for noise attenuation, blast resistance, and extreme weather protection.
- Total System Synergy: The inclusion of 3P Prinz technology seamlessly complements Calder’s established expertise across other heavy-duty pump lines—including API 610 centrifugal systems, API 674 (Hammelmann and NOV) reciprocating plunger pumps, and API 675 double-diaphragm metering packages.
- Complete Auxiliary Outfitting: We supply all required instrumentation, local control panels, variable-speed drives, seal-flush systems, and high-integrity piping networks for a cohesive system.
