Pacer S Series Self-Priming Centrifugal Pumps: The Industrial Standard for High-Performance Fluid Transfer
Engineered for unforgiving environments, the Pacer S Series Self-Priming Centrifugal Pumps deliver heavy-duty fluid management across agricultural, industrial, marine, and waste treatment sectors. Built on a foundation of professional-grade corrosion resistance and high-efficiency fluid movement, the S Series is designed to tackle everything from clean water retrofits to aggressive agricultural chemicals, gray water, and salt water transfer.
By combining lightweight, high-strength thermoplastic construction with a truly modular driving configuration, this series eliminates the choice between rapid portability and long-term chemical durability.
Material Versatility: Armor Against Chemical Attack
The S Series is precision-molded using elite glass-reinforced engineered plastics. This tailored material approach ensures that your internal pump components remain entirely immune to rust, pitting, and structural breakdown caused by aggressive media:
Glass-Reinforced Polyester: The premium, versatile workhorse material ideal for agricultural chemicals, mild acids, bases, brine, and salt water.
Polypropylene: Provides enhanced resistance to specialized industrial process waters and acidic chemical formulations.
Technical Summary
Maximum Flow Rate: Up to 280 GPM on electric configurations, 290 GPM on engine-driven models, and up to 400 GPM on specialized 3" Dupont Rynite layouts.
Maximum Total Dynamic Head (TDH): Up to 120 ft at 60 Hz or up to 126 ft on engine-driven models.
Maximum Shut-Off Pressure: 52 PSI.
Vertical Suction Lift: Reliable self-priming up to 25 feet (7.6 meters) vertical.
Port Configurations: Available in 1½”, 2”, or 3” NPT or BSP threaded configurations.
Intelligence Powered by Mechanical Innovation
The S Series replaces structural complexity with smart, field-proven mechanical advantages that extend pump run life and lower operational costs:
Built-In Fast-Priming Check Valve: Features an integrated check valve that prevents backflow and siphoning. This system maintains liquid within the housing after initial priming, ensuring immediate restarts and rapid self-priming up to a 25-foot vertical lift.
Premium Shaft Seal Construction: Equipped with heavy-duty stainless steel shaft seals featuring carbon and ceramic faces. Specialized configurations offer hardened siliconized graphite shaft seal faces to maximize durability during extreme chemical transfer cycles.
Rugged Double-Flush Volute & Ribbed Body: The advanced double-flush volute geometry prevents sediment settling, while the distinct exterior ribbed body distributes internal hydraulic pressures evenly to prevent casing distortion under high-head loads.
Unified Stainless Steel Fasteners: Utilizing 316 stainless steel internal fasteners and 304 stainless steel external hardware, the S Series prevents seizing and exterior degradation even in humid marine or acidic spraying environments.
Advanced Protek System Engine Protection: For chemical and fertilizer transfer, the unique Protek system physically separates the pump from the engine. This fail-safe design features a large internal cavity, an oversized slinger to block liquid migration, and a double-sized weep hole to protect the engine against catastrophic seal failure.
Multi-Drive Adaptability: Choose Your Power Solution
The S Series features an adaptable bracket design that allows the high-performance wet end to be close-coupled, long-coupled, or pedestal-mounted to virtually any prime mover:
Close-Coupled Electric Drives: Equipped with premium Baldor or Leeson TEFC 60Hz motors spanning from 0.5 HP to 5 HP (and up to 10 HP in long-coupled configurations). Perfect for stationary, automated industrial and agricultural applications requiring continuous, worry-free execution.
Fuel-Driven Portability (Gasoline): Powered by commercial-grade Honda GX Series (GX160 or GX200), professional Briggs & Stratton XR Series, or LCT Maxx and CX Pro engines. These setups feature overhead valve designs, electronic ignition, low-oil alert shutdown systems, large fuel tanks, and optional electric start.
Specialized Hydraulic & DC Drives: Capable of operating seamlessly on open-center or closed-center hydraulic loops up to a maximum input of 9 GPM of hydraulic fluid flow. For mobile utility trucks and marine vessels running off battery banks, specialized 12V & 24V DC close-coupled units with 2" ports are outfitted with fresh/salt water compatible Buna-N elastomers.
