Overview

A pumper built around the crew

A custom pumper puts a purpose-built fire cab, a big pump and the compartment space your crew needs on one chassis — engineered from a clean sheet for the fire service, not adapted from a commercial truck.

Every custom pumper Heiman delivers rides on the Rosenbauer Commander cab-and-chassis, with a fire pump plumbed in-house. You choose the pump position, the body, the seating and the water you carry — and we build the truck around it.

Prefer the value path? The same pump, body and tank options are available on a commercial chassis. Tell us the mission and we’ll price both so you can see the trade.

Pump configurations

Four ways to build it

Pump position and layout are a preference, not a price tier. Every configuration below is built on the Commander custom chassis — pick the one that fits how your crew works.

Config 01
Side Mount

The tried-and-true layout that has run on fleets for decades — familiar, fully serviceable, operator-side controls.

Commander · EXT/FX body · to 1500 GPM

Top Mount

Widely regarded as the safest spot for the operator — elevated for full fireground visibility, up out of traffic, with crosslays low and easy to reload.

Rear Mount

Rosenbauer is the industry leader in custom rear-mount apparatus. Frees compartment space for equipment; controls on operator, back or curb side, flowing multiple lines at once.

When weather is a hurdle, an enclosed panel protects the operator — electric valves or a sealed lever-bank keep controls dry and corrosion-free.

The cab underneath

The Commander custom cab

Every custom pumper rides on the Commander cab — engineered from a clean sheet for the fire service and crash-tested well beyond NFPA. The same crew protection and space that define the flagship chassis carry straight onto your pumper.

01
Crash-tested to protect the crew
Third-party SAE J2422 roof crush held 120,000 lb — nearly five times the requirement — and J2420 front impact came in at 2.27×. That’s the structure around your crew in a rollover.
120,000 lb crush · ~5× NFPA
02
The most crew space in the industry
The engine sits low and rearward on a drop frame, so the tunnel is only 21″ high with tapered 42″ corners — room to seat up to ten firefighters in full turnout on a flat crew floor.
21″ tunnel · seats up to 10
03
Rollover & impact protection
Optional RollTek side-roll protection tightens the belt and deploys a curtain in under 0.3 seconds, with frontal air bags available for the driver and officer.
RollTek <0.3s · airbags
04
Best-in-class HVAC
Integrated automotive-style climate control — 96,000 BTU A/C, 82,000 BTU heat and 3,160 CFM of crew air — conditioning every seat, not just the front.
96k / 82k BTU · 3,160 CFM
05
Clean-air cab
An in-cab air-recirculation scrubber pulls carcinogenic particulates and VOCs from the crew area — 50% VOC reduction in 2 minutes, 80% in 5. New builds or retrofit.
Clean Air · 50% VOC in 2 min
06
Built to see and move
A one-piece windshield with no center post, an automotive-style wrap-around composite dash, wide doors that open to 85° and a flat crew floor with no PTO hump to trip over.

Your custom chassis is built in Wyoming, Minnesota

Every Commander cab-and-chassis under a custom pumper is assembled at the Rosenbauer Motors plant in Wyoming, Minnesota — a facility entirely owned by Rosenbauer America. One manufacturer, engineered and built from the chassis up.

G3 Fire · Tanks built here

Your water tank, fabricated in-house

G3 Fire is Heiman’s own tank shop. Every custom pumper we put in service can carry a G3 Fire water tank — formed from corrosion-proof copolymer polypropylene and fabricated in-house for a precision fit, built and backed by the same team that delivers and services your truck.

  • Copolymer polypropylene — corrosion-proof, won’t rust or rot
  • Built here — fabricated in Heiman’s own shop, not outsourced
  • Custom-fit — sized to your body and baffled to your spec

Options that earn their keep

Built to work. Built to last.

01
Green Star™ idle reduction
Shuts down the chassis engine on scene and runs auxiliary power — a diesel APU or marine battery bank — at about a quarter of the fuel, lowering emissions and stretching oil, DPF and service intervals.
~¼ idle fuel · longer service intervals
02
Electrical your way
Point-to-point wiring for simple troubleshooting, or a Rosenbauer LCS multiplex system with programmable control and load management — on non-proprietary, serviceable parts.

No proprietary lock-in
Built on serviceable, brand-name parts — non-proprietary electrical, standard pumps and fluids — so routine service doesn’t route back through one factory at their markup.

Buy the truck, not the badge

Same capability · less to own
A pumper, not a premium for the name

Let’s be honest about how a lot of these decisions get made. A recognized name on the door carries pride, and a shiny flagship rig looks good in the photo at the council meeting — that pull is real, and every one of us has felt it. But pride and image are an emotion, and emotion is a big part of what the premium is actually buying. The badge doesn’t move more water, build a stronger body, or add a year of service life.

And that premium isn’t coming out of your pocket — it’s the city’s money and the taxpayers’. A Rosenbauer custom pumper gives you the same pump, the same crash-tested custom cab and an EXT body with a lifetime transferable warranty — on serviceable, brand-name parts you can source anywhere. Same fireground capability, a budget you can defend line by line.

Questions to ask yourselves

The answers to these shape the whole build. Work through them with your crew and bring them to the table — we’ll steer you to the right pumper.

Tank size drives axle, wheelbase and price. A custom pumper typically carries 500–1000 gallons; more water means more weight on the road and a longer, heavier truck. Tell us your first-due water needs and hydrant spacing and we'll size the tank to match.
Match the pump to the job. A 1500 GPM single-stage pump covers most departments; add a high-pressure stage and you get CAFS-like flow. Bigger pumps add cost, plumbing and annual NFPA pump-test obligations.
Side mount is familiar and fully serviceable; top mount is the safest spot for the operator with the best fireground view; rear mount frees the most compartment space; enclosed top mount keeps the operator out of the weather. Position is a preference, not a price tier.
The Commander cab seats up to ten with forward-facing SCBA-style seats and NFPA belts. Decide your riding complement now — it sets cab length, door configuration and seating layout.
EXT extruded aluminum is the premium body with a lifetime transferable warranty. FX (formed) in 1/8" or 3/16" aluminum or stainless is the value-focused path. Your budget and expected service life usually decide.
Green Star IRT shuts down the chassis engine on scene and runs auxiliary power at about a quarter of the fuel — saving fuel, emissions and service intervals, and stretching oil and DPF life. Tell us your operation and we'll spec the options that pay off.
Bay door height, bridge weights and tight rural turns all limit the build. Measure your lowest obstruction and tightest approach before we finalize the cab, body and wheelbase so the finished truck fits and clears.
Fire pumps integrate in-house, and all major pump brands are available. Keeping commonality with the rest of your fleet simplifies parts, training and service — tell us if that matters to you.
Compliance

Certified to NFPA 1900

Every custom pumper Heiman delivers is built to the pumper fire apparatus requirements of NFPA 1900 — the consolidated standard that now folds in NFPA 1901.

Fire Pump
Min. 750 GPM

A permanently mounted fire pump rated at least 750 GPM — the defining requirement of a pumper.

Water Tank
Min. 300 gal

Certified minimum tank capacity so the crew can make an initial attack before a supply line is established.

Equipment Storage
Min. 40 ft³

Weather-resistant, enclosed compartment space for the required pumper equipment complement.

Hose Storage
Min. 30 ft³

Hosebed sized for 2½″ or larger supply hose, plus two areas for 1½″ or larger preconnects.

Ground Ladders
Roof + Extension

Carries the standard’s ground-ladder complement — straight roof ladder, extension ladder and folding attic ladder.

Suction / Supply
20 ft hard suction

Or 15 ft of soft supply hose, so the pumper can draft from static sources or take a hydrant.

NFPA 1901 (Standard for Automotive Fire Apparatus) has been consolidated into the comprehensive NFPA 1900. Figures shown are the standard’s minimums for this apparatus type; Heiman and Rosenbauer build to those minimums and well beyond.
