Diesel Engine Coolant Pumps
Many diesel coolant pumps use 30 to 50 year old designs and do not accommodate modern failure prevention techniques. Paragon has developed a series of coolant pumps designed to prevent all common failure modes using proven techniques.
Features and Benefits
10-year service life
No routine maintenance, except periodic oil level checks
Perfectly configured shaft seal
Balanced seal reduces seal face load, which extends life
Seal flush system removes debris from the seal chamber
Seal cooling system prevents damaging high- temperature conditions
Corrosion-resistant seal materials
Balanced hydraulic system minimizes load on bearings
Very high capacity bearings designed to outlive the pump
Serviceable non-contact oil seal for reliability and lowering total cost of ownership
Efficiency > 80%
Fuel Transfer Pumps
Paragon’s diesel engine fuel transfer solutions are marketed to a wide range of large diesel engine manufacturers and end users in a diverse array of industries. The pumps are modeled after our exceptionally reliable locomotive pumps, which have been field-proven under the most grueling conditions for more than 25 years.
The most reliable, best value diesel fuel pumps on the market
They typically outlast other pumps 3:1, saving cost of downtime, labor, and parts
Brushless 74 or 24 volt DC or 230/460 VAC inverter controlled induction motor
Integral, fluid cooled DC/AC inverter for ultimate electronics reliability
Continuously lubricated, self-cleaning bearings for optimal life
Positive displacement gear pump with excellent self-priming capabilities
Hardened pump body and gears to resist fuel contaminants
Capacities from 2 LPM to 60 LPM (0.5 GPM - 16 GPM)
Outlet pressures of up to 8.3 Bar (120psi) continuous duty
Paragon Products DC diesel pumps are standard equipment on most locomotives in North America
A pre-lube system provides vital protection to your costly equipment by delivering oil under pressure to the most critical components when they are the most vulnerable to wear — during equipment startup.
Engines, compressors, turbo machinery, motors, generators, transmissions, and all other heavy mechanical equipment have means of lubrication during operation. But with mechanically driven lube pumps, the hot lube oil drains back into the oil sump after shutdown, leaving vital moving parts with only a thin film of residual oil to handle enormous loads during startup. The result is premature wear.
Also, recent emissions and fuel conservation regulations requiring frequent start/stop protocol exacerbate mechanical wear conditions.
Paragon Products' diesel engine fuel priming pumps are designed for exceptional reliability and a long, maintenance-free life. They accommodate flow rates of 2 to 100 LPM (0.5 GPM - 30 GPM) with brushless DC or AC motors.
Pressure Relief Valves
Managing fuel pressure to accommodate the needs of today’s diesel engines is crucial to the integrity of the system and to the life of fuel system components. Paragon Products’ pressure relief valves provide this peace of mind and help protect filter housings, hoses, fittings, seals, and pumps by eliminating pressure spikes and irregularities.
Paragon's valves satisfy manufacturers' recommendations by offering a number of precision pressure relief units, all based on one versatile and robust package. Valves can be set to relieve pressure ranging from 0.1 to 10.4 Bar (2 to 150 PSI), while flow rates can be adjusted from 0 LPM to 53.2 LPM (0 - 14 GPM). Valve cracking pressure and piston dampening can be customized to meet unique performance requirements. Units with field adjustability are also available.
Turbo Soak-Back Pumps
Turbo soak-back pumps are used for turbocharger lubrication and cooling immediately upon engine shutdown, avoiding expensive and unnecessary turbocharger failures. It functions as a turbo pre-lube pump as well providing vital protection during startup.
Features and Benefits
Designed for frequent start/stop cycles (AESS)
Brushless induction motors eliminate the cost and downtime of regular brush replacement
DC power input
Liquid-cooled electronics to prevent heat-related failures
Continuously lubricated, self-cleaning bearings for better and more consistent performance over the life of the product
Hardened pump body and gears maximize longevity
Capacity 13 LPM (3.5 GPM), differential pressure of 2.8 bar (40 PSI)
Other sizes and voltages on request
Can double as an engine pre-lube pump or turbo pre-lube pump
Paragon Products soak-back pumps are designed for a maintenance -free life of 10 years on heavy-duty equipment.
