EV Pump & Equipment rents bypass, trash, submersible, diaphragm, sound-attenuated, and high-volume water pumps to industrial sites across Louisiana, the Texas Gulf Coast, Mississippi, and parts of Arkansas - most on a truck within 24 hours of the call. |
This guide covers when it makes sense to rent instead of buy, the best use cases for rental equipment, what we keep in the fleet, how fast we can deliver, and what to have ready when you call for a quote.
Renting makes sense whenever the math on owning the pump doesn't pencil out - short jobs, emergencies, or any time you need a unit running before a purchase order could clear. Three situations where renting beats buying every time:
One-time job or short project. You've got a six-week dewatering job, a one-shift bypass, or a turnaround coming up next month. Putting $40,000 into a pump that sits on a yard the other 50 weeks of the year doesn't pencil out. Rent it, use it, send it back.
Emergency or uptime situation. A pump went down at 2 a.m. and the line can't sit idle. You don't have time to spec a new unit, wait six weeks for delivery, and commission it. You need something running today. That's what a rental fleet is for.
Testing before you spec a permanent install. Engineers and maintenance managers come to us when they're sizing a pump for a new process and want to confirm performance before committing to a purchase order. Rent the type you're considering, run it on the actual fluid at the actual flow rate, and you'll know whether the spec sheet matches reality.
Buying still makes more sense when the pump will run regularly enough to justify the capital, the maintenance, and the warehouse space. If you're not sure which side of the line you're on, give us a call.
Once you've decided renting is the right call, the next question is which pump fits which job. Here's what we move most often, and what each kind of job typically calls for:
Construction and site dewatering. Foundation work, excavation, and post-rain pumping where a pump runs hard for weeks or months and then isn't needed again. Trash pumps and self-priming centrifugals are the workhorses here.
Plant turnarounds and shutdowns. Temporary capacity during planned maintenance — running a bypass while a permanent unit comes offline, transferring fluid during tear-downs, or supporting commissioning work after the turnaround wraps.
Sewer line and lift station bypass. Municipal water and wastewater projects where the line has to keep flowing while crews work on a section downstream. Skid-mounted bypass packages with the hose and fittings already matched.
Storm and flood response. Gulf Coast reality. When water shows up where it isn't supposed to be, high-volume pumps and submersibles move it out fast. We keep emergency-ready units on hand for hurricane season.
Saltwater disposal and oilfield support. Short-term boosts, well site standbys, or temporary units while a permanent pump is rebuilt. We send a lot of equipment to operators in South Louisiana and East Texas on this kind of work.
Tank cleaning and fluid transfer. Diaphragm and trash pumps for one-off transfers, vessel cleanouts, and waste handling jobs where a dedicated pump doesn't earn its place on the yard.
We work with operators in oil and gas, saltwater disposal, petrochemical, municipal water and wastewater, agriculture, mining, and general industrial. If your job doesn't fit cleanly into one of the categories above, call anyway. Most rentals start with a conversation about what's actually happening on-site, and we'll spec from there.
We rent the workhorse equipment for Gulf Coast industrial work - bypass packages, high-volume water pumps, trash pumps, self-priming centrifugals, diaphragm pumps (air and gas-powered), sound-attenuated units, and submersibles.
Here's the breakdown:
|
Pump type |
What it's for |
Notes |
|---|---|---|
|
Bypass pumping packages |
Plant turnarounds, lift station bypasses, sewer line repairs |
Skid-mounted with hose, fittings, and controls included |
|
High-volume water pumps |
Construction dewatering, flood response, large water transfer or dredging |
Diesel-driven, trailer-mounted |
|
Dewatering with debris, mud, or solids in the water |
When a standard centrifugal can't handle the slurry |
|
|
Sump work, general dewatering, pump above the water line |
No foot valve needed |
|
|
Chemical transfer, abrasive slurry, shear-sensitive fluids |
Runs off plant air |
|
|
Gas-powered diaphragm pumps |
Same applications, field-portable |
No plant air or generator required |
|
Sound-attenuated (quiet) pumps |
Job sites near homes, hospitals, hotels |
Same flow, fewer noise complaints |
|
Submersibles |
Deep dewatering, manholes, sumps - anywhere the pump sits in the fluid |
Light-duty to heavy industrial sizes |
For abrasive or chemically aggressive slurries that chew up standard pumps, we also stock peristaltic pumps - worth a call if that's your situation.
Most rentals come ready to run. That includes the pump, suction and discharge hose in standard sizes, fittings, and basic controls. If you need anything beyond the standard package (longer hose runs, specialty fittings, fuel delivery, generator power) tell us when you call and we'll spec it into the quote.
If you don't see what you need on the list, give us a call anyway. We've got relationships with manufacturers and other distributors across the region, and we can usually source what you need even when it's not on our shelf today.
For most equipment on our list, we can have a pump on a truck and headed your way within 24 hours of the call - often the same day if you catch us before noon. We're based in Scott, Louisiana, just outside Lafayette, which puts most of the Gulf Coast within a half-day's drive.
Routine delivery areas:
South Louisiana — Lafayette, Houma, New Iberia, Baton Rouge, Lake Charles, New Orleans
Texas Gulf Coast — Beaumont, Port Arthur, Orange, Houston
Mississippi and parts of Arkansas
East Texas and Southwest Louisiana oilfield sites
For unusual sizes or specialty units, give us a 48-hour window so we can confirm availability or stage the right configuration. Either way, we'll tell you when you call we won't promise a window we can't hit.
The right pump for a job depends on more than what you're moving — it depends on how much, how far, in what conditions, and for how long. Before you reach out for a quote, here's what to think through:
Flow rate — how many gallons per minute do you need to move?
Suction lift and discharge head — how far is the pump from the fluid, and how far does it need to push?
What's in the fluid — clean water, debris, chemical, sand, sewage, oil?
Duration — a day, a week, several months?
Hose and fittings — what's already on-site, and what do you need us to bring?
Power source — diesel, electric, air, or gas-powered?
Location and access — can a service truck get to the drop point?
You don't need every answer locked down before you call, we can walk through the gaps with you. But the more you've thought through, the faster we can spec the right unit and get it on a truck.
Rental pricing depends on the pump type and size, the duration, and what accessories you need (hose, fittings, fuel, generator). We quote daily, weekly, and monthly rates — the per-day cost drops as the rental gets longer. Call (337) 252-6487 with the basics on your job and we'll give you a number on the same call.
Delivery and pickup are quoted separately based on distance from our Scott, LA yard. We include the round-trip in the original quote so there are no surprises on the invoice. For nearby Gulf Coast sites, delivery is usually a small fraction of the total rental cost.
You handle fuel and basic operator checks — oil level, hose condition, ground placement. We handle anything that requires a mechanic. For long rentals, we can build in scheduled service visits (oil changes, filter checks, hose swaps) so the unit stays running. Tell us what your job needs when you quote and we'll write it into the agreement.
If the unit fails through normal mechanical wear or a manufacturing issue, that's on us — call and we'll fix or swap. If it's damaged from accident, misuse, or environmental factors (forklift impact, debris pulled in past the strainer, that kind of thing), that's typically covered under your job-site insurance or the rental agreement. We walk through the unit with you at delivery so we both know its condition going in. Either way, if something goes wrong, the answer is the same: call us.
Most rentals go out unmanned — your crew runs the pump. At delivery, we walk through start-up, basic operating procedures, and shutdown so whoever's on the job knows what they're working with. If you need a tech on-site for setup, troubleshooting, or longer support, we offer mobile service separately.
