Three pumps cover 5 through 10 HP and 145 through 200 PSI maximum pressure. Every one is a Champion factory pump built in Princeton, Illinois, not an aftermarket copy, so it drops onto an existing Value Plus base with the same mounting pattern, the same flywheel geometry and the same service parts.\u003c\/p\u003e\n\n\u003cp\u003eA bare pump is the right purchase in two situations: an existing VP-Series compressor has worn out its pump but still has a sound motor, tank and starter, or a builder wants to specify the motor, receiver and controls separately. Buying the pump alone is substantially cheaper than replacing the whole package and keeps the tank's ASME paperwork and installation intact.\u003c\/p\u003e\n\n\u003ch2\u003eModel selection chart\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePump model\u003c\/th\u003e\n\u003cth\u003eOrder entry #\u003c\/th\u003e\n\u003cth\u003eHorsepower served\u003c\/th\u003e\n\u003cth\u003eStages\u003c\/th\u003e\n\u003cth\u003eCylinders\u003c\/th\u003e\n\u003cth\u003eMax pressure\u003c\/th\u003e\n\u003cth\u003ePump RPM\u003c\/th\u003e\n\u003cth\u003eShip weight\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-40\u003c\/td\u003e\n\u003ctd\u003eVP-40-CH\u003c\/td\u003e\n\u003ctd\u003e5 HP\u003c\/td\u003e\n\u003ctd\u003eSingle stage\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003e145 PSI (10.0 bar)\u003c\/td\u003e\n\u003ctd\u003e1200\u003c\/td\u003e\n\u003ctd\u003e72 lb (33 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-55\u003c\/td\u003e\n\u003ctd\u003eVP-55-CH\u003c\/td\u003e\n\u003ctd\u003e5 and 7.5 HP\u003c\/td\u003e\n\u003ctd\u003eTwo stage\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003e180 PSI (12.4 bar)\u003c\/td\u003e\n\u003ctd\u003e800\u003c\/td\u003e\n\u003ctd\u003e119 lb (54 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-100\u003c\/td\u003e\n\u003ctd\u003eVP-100-CH\u003c\/td\u003e\n\u003ctd\u003e7.5 and 10 HP\u003c\/td\u003e\n\u003ctd\u003eTwo stage\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003ctd\u003e200 PSI (13.8 bar)\u003c\/td\u003e\n\u003ctd\u003e500\u003c\/td\u003e\n\u003ctd\u003e254 lb (115 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eBore and stroke\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePump model\u003c\/th\u003e\n\u003cth\u003eBore and stroke (inches)\u003c\/th\u003e\n\u003cth\u003eBore and stroke (mm)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-40\u003c\/td\u003e\n\u003ctd\u003e2-1\/2 bore x 1-7\/8 stroke\u003c\/td\u003e\n\u003ctd\u003e65 x 46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-55\u003c\/td\u003e\n\u003ctd\u003e3-1\/8 (2 cyl) and 2-1\/2 (1 cyl) x 2-3\/8 stroke\u003c\/td\u003e\n\u003ctd\u003e80 (2) and 65 (1) x 60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVP-100\u003c\/td\u003e\n\u003ctd\u003e4-1\/8 (2 cyl) and 2-1\/8 (2 cyl) x 3-1\/2 stroke\u003c\/td\u003e\n\u003ctd\u003e105 (2) and 55 (2) x 89\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eShared technical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubrication:\u003c\/strong\u003e splash lubricated, no oil pump, no oil filter and no pressure feed system to fail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e cast iron cylinders and crankcase, ductile iron or cast iron flywheel acting as the cooling fan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValves:\u003c\/strong\u003e Champion disc valve assemblies, serviceable from the head without pulling the pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntercooler:\u003c\/strong\u003e fitted on the two-stage VP-55 and VP-100; the single-stage VP-40 has none\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e belt drive from a separately supplied motor; pump RPM as listed above, which is what sets the correct sheave ratio\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty:\u003c\/strong\u003e intermittent duty, sized for roughly a 50 to 75 percent duty cycle in normal shop service\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied as:\u003c\/strong\u003e bare pump only.

Air is compressed in a large low-pressure cylinder, cooled through an intercooler, then compressed again in a smaller high-pressure cylinder. Two-stage compression runs cooler, delivers more air per horsepower and reaches 180 and 200 PSI respectively. If an application needs more than about 150 PSI, or runs for long stretches, a two-stage pump is the one to specify.\u003c\/p\u003e\n\u003cp\u003eNote that the VP-55 is rated for both 5 and 7.5 HP and the VP-100 for both 7.5 and 10 HP. The horsepower a given pump is driven at is set by the motor and the sheave ratio, not by the pump casting, so confirm the existing motor nameplate and sheave sizes before ordering a replacement.\u003c\/p\u003e\n\n\u003ch2\u003eIdeal applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReplacement pump for a worn Champion Value Plus VP5-40-6, VP5-55-8 or VP7-100-8 stationary compressor\u003c\/li\u003e\n\u003cli\u003eAutomotive and truck service shops running impact tools, lifts and tire equipment\u003c\/li\u003e\n\u003cli\u003eAgricultural and equipment maintenance shops where 175 to 200 PSI is wanted for tire service\u003c\/li\u003e\n\u003cli\u003eCustom-built packages where the motor, receiver and control panel are specified separately\u003c\/li\u003e\n\u003cli\u003eOEM machine builders who need a known-quality cast-iron pump with published bore, stroke and RPM data\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eService and accessories\u003c\/h2\u003e\n\u003cp\u003eChampion publishes a service kit for each pump, containing the oil and air filters for a routine service interval.

These pumps ship from the Champion factory in Princeton, Illinois with full factory warranty, which an aftermarket or grey-market pump does not carry. We stock and sell the whole Champion reciprocating range, so if the pump turns out not to be the right fix we can quote the complete package, the motor, the receiver or the controls in the same conversation. Orders over 400 pounds ship freight prepaid and allowed under Champion's reciprocating shipment terms.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the pump come with a motor or a belt guard?\u003c\/strong\u003e\u003cbr\u003eNo. A bare pump is the pump only. Motor, sheaves, belts, belt guard, base, receiver, pressure switch and all controls are supplied separately. If you need the complete machine, buy the packaged VP-Series compressor instead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich pump replaces the one on my VP-Series compressor?\u003c\/strong\u003e\u003cbr\u003eThe VP5-40-6 uses the VP-40, the VP5-55-8 uses the VP-55 and the VP7-100-8 uses the VP-100. The pump model is also stamped on the pump itself. If the nameplate is unreadable, count the cylinders: three cylinders with no intercooler is a VP-40, three cylinders with an intercooler is a VP-55 and four cylinders is a VP-100.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat oil do these pumps take?\u003c\/strong\u003e\u003cbr\u003eChampion splash-lubricated reciprocating pumps take a non-detergent compressor oil. Champion's own ChampLub mineral ISO 100 is the factory fill. Do not use automotive engine oil; the detergents carry over into the air stream and attack downstream seals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I run the VP-100 at 10 HP?\u003c\/strong\u003e\u003cbr\u003eYes, it is rated for 7.5 and 10 HP. The horsepower is set by the motor and the sheave ratio, so a 10 HP build needs the correct sheave combination to hold the pump at its published 500 RPM. Driving a pump above its rated RPM shortens valve and bearing life sharply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs a two-stage pump always better?\u003c\/strong\u003e\u003cbr\u003eNot always. Two stage gives higher pressure and better air per horsepower, but it costs more and the VP-40 is perfectly matched to a straightforward 5 HP, 125 PSI shop. Specify two stage when the job needs above about 150 PSI or the compressor runs for long periods.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre dimensional drawings available?\u003c\/strong\u003e\u003cbr\u003eChampion publishes bore, stroke, cylinder count and shipping weight for these pumps, which are reproduced in full above, but the August 2026 price book carries no overall dimensional drawing. Contact us and we will request the current drawing from the factory before you commit to a mounting design.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003ePricing reflects the Champion Reciprocating Price List effective August 15, 2026.
