Discharge Port: 1-1/2 inch NPTF, typically with three outlets "DISCHARGE 1-1/2 NPTF (3 PORTS)".
G. Physical Characteristics
Overall Dimensions (L x W x H): The basic pump unit is approximately 35-1/8" L x 24-3/4" W x 26-1/4" H (892mm x 629mm x 667mm).
Weight: Approximately 750 lbs (340.2 kg), with an aluminum bronze fluid end weighing 750 lbs, a ductile iron fluid end weighing 730 lbs, and a forged steel fluid end weighing 775 lbs.
Fluid End In-depth Analysis: Design, Materials, and Manufacturing Precision
Fluid Cylinder (Fluid Cylinder / Liquid Block)
Material Specifications: Various ASTM-compliant material options are available to suit different applications and fluid compatibility requirements:
Ductile Iron: ASTM A536 80-55-06 (provides good strength and certain corrosion resistance).
Carbon Steel: ASTM A36 (general-purpose, good strength).
Stainless Steel: 316 S.ST. or 2205 Duplex S.ST. (provides excellent corrosion resistance for more corrosive fluids).
Valve System Integrity
Type: "Double Stem-Guided" valve array is standard.
Disc Valves: Acetal resin (Acetal), 17-4PH Stainless Steel (17-4PH SS T), Titanium.
Abrasion Resistant (AR) Valve: 17-4PH Stainless Steel (17-4 PH S.ST.).
Valve Materials:
Valve: 17-4PH Stainless Steel is a common high-strength, corrosion-resistant material suitable for abrasion-resistant valves and an optional material for disc valves.
Spring Material: Valve springs are specified to use Inconel® alloy, a material renowned for its excellent corrosion resistance and performance in high-temperature and high-stress applications.
Plunger/Piston
Material Options and Surface Treatment:
Standard Configuration: Rokide® coated 316 Stainless Steel plungers. "Rokide" is a chromium oxide coating known for its extremely high hardness and low coefficient of friction, providing excellent wear and corrosion resistance.
Optional Configurations: Tungsten Carbide and Ceramic plungers are also available for enhanced durability in highly abrasive or corrosive conditions.
The SC-65L data sheet specifically mentions "3.000 PISTON", indicating that for this maximum size, a piston with piston cups design is used, rather than a solid plunger.
Piston Cup Materials (for 3.00 inch size):
"Supergold" or "GOLD" piston cups are available, typically made of HSN (Highly Saturated Nitrile Rubber) and Aramid Fiber (Kevlar®), suitable for abrasive conditions. It is mentioned that "Supergold" piston cup material for SC-65L is HNBR with Kevlar® or NBR with cotton fabric. Buna-N (Nitrile Rubber) is a common general-purpose sealing material and may also be offered as an option.
Cylinder Liners
Material Options:
Ceramic Liner with Steel Jacket: Available in various sizes, including 3.00 inch ID for SC-65L. Ceramic (typically alumina or zirconia) offers excellent wear and corrosion resistance.
Hardened Chrome Liner: Another option, generally more cost-effective, providing good wear resistance. Suitable for 3.00 inches in the SC-65L. Aplex pumps also mention high-chrome cast iron alloy liners (≥27% Cr, HRC 60-65).
Wear-Resistant Design: Liners are field removable and replaceable. The choice between ceramic and chrome depends on the fluid's abrasiveness and budget.
Packing and Sealing Technology
Stuffing Box Material: Specified as Carbon Steel (1020) for field-removable and replaceable stuffing boxes.
Available Packing Types (for plungers): Various packing forms are available to meet different sealing needs and operating conditions:
Gland-loaded, Non-Adjustable: Style 838.
Spring-loaded, Braided PTFE coating and Aramid Fiber (Kevlar®): Style 140, 141, 8921K. These types provide good chemical resistance and durability for abrasive applications.
Spring-loaded, cup-type: Style 120X.
Static Sealing Materials (Valve Cover, Stuffing Box): Buna-N (Nitrile Rubber) is listed as the standard material for these seals, offering good general resistance to oils and various chemicals.
Manufacturing Process of Fluid End Components
Key components such as the fluid cylinder block, plungers, and liners are manufactured using processes that ensure precision and durability. These processes include:
Casting/Forging: The fluid cylinder block and other structural components may be formed by casting (ductile iron, stainless steel) or forging to ensure strength.
Precision Machining (CNC): Critical dimensions such as sealing surfaces, plunger bores, and valve seats are achieved through precision machining (most likely CNC machining) to ensure tight tolerances and correct fit.
Surface Treatment: Rokide® coating on plungers and hardening of chrome-plated liners are specialized surface treatment processes designed to enhance wear and corrosion resistance.

Manufacturing Process: Typically forged for high strength, then precision machined and ground to ensure accuracy of journal dimensions and surface finish.
Crankshaft Diameter: Drive end extension: 2.500/2.499 inches; at tapered roller bearing: 3.35 inches; at crankpin bearing (diameter x length): 2.750 inches x 2 inches.
C. Connecting Rod
Material: Automotive Type Ductile Iron.
Design Features: Likely features a split big end design for easy assembly on the crankshaft crankpin, which is a common structure for automotive-grade connecting rods.
D. Crossheads
Material: Full Cylindrical Cast Iron.
Design and Dimensions: Used to guide the plunger/piston rod assembly and absorb side forces. Diameter x Length: 4 inches x 4-1/2 inches.
E. Crosshead Pin and Bushing
Crosshead Pin Material (Wrist Pin Material): AISI 8620 Case-Hardened and Ground steel. This treatment provides a hard, wear-resistant surface and a tough core.
Wrist Pin Bushing Material: SAE 660 Bronze. SAE 660 is a common bearing bronze known for its good wear resistance and anti-friction properties.
F. Bearing System
Main Bearing Type: Tapered Roller Bearings, specified brand Timken®. These bearings are suitable for combined radial and axial loads.
Main Bearing L10 Design Life: 30,000+ hours. L10 life means that 90% of such bearings are expected to achieve or exceed this operating life under the rated conditions.
Connecting Rod Bearing (Crankpin Bearing) Type: Precision Automotive, Steel Backed, Babbitt-Lined. This type of bearing offers good conformability and embeddability.
G. Lubrication System
Type: Splash & Scoop system. This is a simple and reliable method where rotating parts splash oil onto various components, and scoops may direct oil to specific areas.
Recommended Lubricant Specifications: S.A.E. 40 wt. non-detergent oil, with anti-foam additives and good water separation (demulsifying) properties, typically labeled as "industrial grade" or "turbine grade" lubricant. If these oils are not readily available, high-quality gear oil or EP oil can be used as a substitute.
Oil Capacity: 8 U.S. Quarts.
Recommended Change Interval: First oil change for new pumps after 500 hours of operation. Subsequent changes every 1,500 operating hours, or earlier if the oil becomes contaminated. Splash and scoop lubrication is a common, simple, and reliable system for these types of pumps, requiring almost no maintenance apart from oil level checks and periodic changes.
Pony Rod (Small Piston Rod/Pony Rod):
Material: 416 S.S.. Diameter: 1-1/4 inches.
Connects the power end crosshead to the fluid end plunger, passing through the wiper ring box to prevent crankcase oil from contaminating the pumped fluid, and vice versa.
Wiper Ring Box Assembly: Includes Poly Pak rings and oil seals, used to seal the pony rod.
