Formula for Success:
PRESTIL is a high-tech manufacturer built on a foundation of experienced professionals and a continuous drive to improve core technologies. Our focus on innovation and quality ensures exceptional production speed, durability, and field performance.

Our sucker rod pumps (SRP) are engineered to operate under the most demanding conditions — delivering reliable fluid lifting from depths up to 2,500 meters, withstanding high water cut (up to 99%), formation temperatures up to 130°C, solid content up to 1.3 g/L, and corrosive elements including H₂S and CO₂ up to 200 mg/L, and mineralized water with pH from 4.0 to 8.0.

Applications

• Wells with high sand and solids content

• Heavy or viscous oil production

• Aggressive and corrosive environments

• Fields requiring durable, low-maintenance artificial lift solutions

Key Advantages

• Enhanced pump efficiency and lifespan

• Protection against plunger and barrel wear

• Reliable performance in high-solids and high-water-cut environments

Engineering Features

• Precision-fitted plunger adapters with sprayed metal coatings and beveled leading edges

• Corrosion-resistant materials for plungers and pump internals

• Exact clearances designed to reduce friction and extend service life

All PRESTIL downhole rod pumps and components are manufactured in compliance with API 11AX and GOST 31835-2012 standards, ensuring full compatibility with industry systems and easy interchangeability with parts from other manufacturers.

Proven Field Performance

• Pump 20-125 RHAM 14-4-2-2: Operated for 465 days at 2,680 m (Campanian, PJSC Ukrnafta)

• Pump 25-175 RHAM 14-4-2-4: Operated for 386 days at 2,350 m (Sukhodolsky, PJSC Ukrnafta)

• Corrosion-resistant models (RHBM series with full stainless steel construction and nickel-phosphorus coated barrels) are running in multiple fields (Tanyavskoye, Kozievsky, Bugrevatovskoye) since 2019.

   

Advanced Components

Sand Diverter
A specialized plunger assembly that redirects sand and particulates away from the pump barrel, preventing premature wear and maintaining stable pump performance. Its beveled, precision-fit adapter prevents fines from collecting between barrel and plunger.

Pressure-Activated Plunger
Equipped with split nylon rings that expand under pressure to enhance sealing during the upstroke and relax during the downstroke. Ideal for wells with poor lubrication or high water cut, the plunger ensures long service life and increased efficiency.

Grooved Plunger Design
Grooves retain lubricants and guide sand, wax, and debris through staged clearance zones. This prevents scoring and increases operational time between pump interventions.

Double Valve Design
Provides added durability and resistance against early valve failure in difficult production environments.

Sand Cleaner
Mounted above the insert pump, this two-piece device prevents solids from settling into the pump during shut-in periods. Molded rubber fins act as a barrier and are easily replaced during maintenance. Available in stainless steel, brass, and carbon steel.

Full-Flow Cage Valve
This valve maximizes internal flow area (+200%) while minimizing pressure drops. It excels in handling heavy crude, wax, scale, and solids with increased pump efficiency and durability.

Barrel Types & Coatings

Chrome Barrels (1026 Carbon Steel)
Compliant with API 11AX and NACE MR0176 standards. Optionally available with double chrome plating for enhanced abrasion resistance.

Chrome Brass Barrels (443 Admiralty Brass)
Superior corrosion resistance in low pH environments. Brass minimizes galvanic corrosion between substrate and plating, extending service life.

Chrome Stainless Steel Barrels (501 SS)
Recommended for severe service wells — exceptional corrosion and wear resistance, ideal for abrasive fluids with mild H₂S or CO₂ content.

Duplex Chrome Plating

PRESTIL offers double-layer chrome plating (0.003"–0.006" per side) on steel, brass, and stainless barrels. Compared to traditional plating, PRESTIL chrome features a dense microcrack structure and <15% porosity — minimizing substrate exposure and dramatically improving corrosion resistance.

PRESTIL Chrome vs Traditional Chrome
Traditional chrome coatings contain macrocracks that accelerate corrosion. PRESTIL chrome offers superior protection by preventing crack propagation and isolating corrosive agents.
