AR Industrial Pump Series: 4 To 52.8 GPM

The AR industrial pump series spans 4 to 52.8 GPM and 1,200 to 11,600 PSI across eight or nine ranges with letter names that give away nothing. The useful question is not which one is best, it is which half of the flow-versus-pressure trade your job sits on.

Here is the range sorted that way.

AR industrial pump series: volume families

Series	Flow	Pressure	Typical work
RTF	36 to 44 GPM	1,500 PSI	Tank flushing, bay washdown, manifolds
XWP	13 to 18.5 GPM	1,740 to 2,200 PSI	High-volume rinse and sanitation
XWL / XWLA	8.7 to 13.2 GPM	1,200 to 3,000 PSI	Fleet wash, food plants, commercial

Pressure families

Series	Flow	Pressure	Typical work
RTP	6.6 to 10 GPM	7,250 to 11,600 PSI	The pressure ceiling of the range
SHP / SHPA	4 to 5.8 GPM	7,000 to 7,250 PSI	Hydroblasting, coating removal, cutting
RF	5.8 to 10.3 GPM	5,800 PSI	High pressure with real flow behind it

The middle, mostly hydraulic

Series	Flow	Pressure	Typical work
RTX	7.9 to 39.6 GPM	1,450 to 7,250 PSI	The widest spread in the range
RTD	21 to 52.8 GPM	1,200 to 4,350 PSI	The largest pumps AR makes
RTJ	18 to 18.5 GPM	4,000 PSI	Sewer jetting, food plant washdown

Hot water and stainless cut across all of it

Two conditions change which version of a pump you need, and they are different conditions.

Heat is handled by the HT and hot-water builds: XWAM8G35NHT, XWF3617-AISC, RTD-HW80-300H. The difference is the seals.

Chemistry is handled by a stainless head: the stainless range, including RTX-SS100.100N and RTDSS80-300N with a food-grade head.

A hot water rating does not confer chemical resistance and a stainless head does not confer temperature rating. If you have both problems, specify both.

What they share

Solid shafts from 18 to 35 mm, for pulley drive, gearbox or direct motor coupling
Forged brass or nickel-plated heads
Ceramic plungers, which is what survives abrasion at these pressures
Stainless valves
Oversized crankcases, 32 oz up to 110 oz, doing the cooling
Low speed: 800, 1,000, 1,450 or 1,750 RPM depending on family. This is most of why they last.

Start from the drive

EBHP is GPM times PSI divided by 1,460, and across this range that runs from about 14 HP to nearly 70. Once you add margin you are specifying 20 to 75 HP motors and three-phase service.

That usually constrains the choice more than the cleaning requirement does, so establish it first. The same applies to water: a 40 GPM pump needs 40 GPM delivered continuously at positive inlet pressure, which is a supply system rather than a hose.

Where AR industrial pumps are used

Hydroblasting and surface prep: paint, rust, coatings, concrete
Construction and demolition: forms, scaffolding, machinery, dust suppression
Marine and shipyards: hulls, bilges, dock maintenance, restoration
Municipal: sidewalks, graffiti, bridge washing, fleet maintenance
Oil, gas and energy: rigs, refineries, tank sanitation, offshore washdown
Agriculture and food processing: USDA-compliant sanitation and equipment cleaning
Manufacturing: degreasing, conveyors, steel prep, floor washdown

Why rebuildable matters at this price

Every family is supported with valve, piston, seal and oil kits. At industrial prices that is not a convenience feature, it is the whole ownership case: a rebuild is a fraction of a replacement, and a maintained pump runs for many thousands of hours.

Know your flow and pressure? Send those plus your available electrical service and water supply and you will get a model the whole installation can actually support.
