Screw Pump FAQs

What type of fluids can the Screw Pump handle?
The Screw Pump is engineered for highly demanding process media, including high-viscosity fluids, abrasive slurries, and solids-laden mixtures. It reliably handles viscosities up to 1,000,000 cP and solids content up to 40–60% (depending on configuration and material selection). Typical applications include drilling mud, oil sludge, refinery bottom residues, wastewater sludge, and industrial chemical slurries.
How does the pump perform in abrasive and corrosive environments?
The pump is designed for severe service conditions in oil & gas, mining, and wastewater industries. Critical wear components such as rotor and stator are available in hardened alloys and engineered elastomers (NBR, EPDM, FKM/Viton). Optional stainless steel and duplex steel construction provides enhanced resistance in corrosive media such as saltwater, sour crude, and chemically aggressive sludge.
Is the Screw Pump suitable for continuous 24/7 operation?
Yes. The progressive cavity design delivers smooth, low-pulsation flow with minimal internal turbulence, making it well-suited for continuous duty. When correctly selected and operated within design parameters, the pump supports stable 24/7 operation in demanding systems such as drilling waste treatment, mud circulation, and sludge transfer applications.
What is the maintenance requirement and expected service life?
The pump is designed for low maintenance and simplified servicing. Primary wear parts, including rotor and stator, can be replaced quickly to reduce downtime. In abrasive service, operators commonly report 2–3× longer stator life compared with conventional pumping solutions, depending on fluid characteristics and operating conditions.
Can the pump be integrated into existing systems and equipment?
Yes. The Screw Pump is highly modular and supports horizontal, vertical, hopper-fed, and skid-mounted configurations. It is fully compatible with variable frequency drives (VFD) for flow control and integrates easily into drilling waste management systems, mud recycling units, HDD/TBM tunneling systems, refinery sludge handling packages, and chemical dosing systems.
How does the Screw Pump perform in remote or low-maintenance locations?
The pump is engineered for high operational reliability in remote and harsh environments such as the Middle East oilfields, African mining sites, offshore platforms, and remote drilling locations. Its robust mechanical design, solids-handling capability, and optional dry-run protection reduce operational risk where maintenance support and spare parts availability may be limited.
