What products and equipment do you sell?

We have everything you need for professional pressure cleaning, including pressure washers for residential and commercial cleaning, surface cleaners for driveways, patios and decks, hoses, nozzles, guns, reels, pumps and accessories. We also custom build pressure cleaning trailers and skids to your exact specifications. All of our products are professional-grade and used by contractors, detailers and cleaning professionals across the country.

Do you build custom pressure cleaning trailers or skids?

Yep, we do. Our team of experts can design and build custom pressure cleaning trailers and skids that are tailor-made to your specific business requirements. You can choose your tank size and capacity, pump power and pressure rating, hose reel configuration and more. We'll build everything into a rugged, easy-to-use setup that is mounted on a trailer (or skid if you're on-site) and ready to go wherever you need to do your cleaning.

Can I finance my purchase?

Yes, you can. We've partnered with ClickLease to make financing simple and flexible for your equipment purchases.

What is your return and refund policy?

Most new unopened merchandise is returnable within 30 days of delivery. Contact us prior to shipping any merchandise back to us for a Return Material Authorization (RMA). All returned merchandise must be shipped via UPS or FedEx. Shipping charges paid on the original order are non-refundable unless the merchandise is defective. Customers pay all return shipping charges. Opened, unused merchandise may also be returned within 30 days of delivery if in like-new condition, subject to a 25% restocking fee. Once fuel or oil is added to engine-powered equipment, it is considered used and is not returnable. Returns are not accepted on custom and special order products. Orders that have shipped can not be cancelled, and may be subject to an Order Return Fee if refused. Please see our Return & Refund Policy for more details.

What payment methods do you accept?

We accept all major credit and debit cards, including Visa, MasterCard, American Express, and Discover. You can also pay easily and securely using Google Pay, Apple Pay, or PayPal at checkout. We have flexible financing options available through Affirm and Klarna, and for larger business equipment orders, financing is available through our partner ClickLease.

Do I need a California-compliant pressure washer?

Yes. If you are using your pressure washer in California, it must be CARB compliant. California law requires that all pressure washers sold and operated in the state to adhere to strict emission standards set by the California Air Resources Board (CARB). The use of non-compliant equipment is subject to fines and confiscation by authorities. Purchasing a non-compliant pressure washer outside of California is not an option if you intend to use it in the state, as it will also need to be CARB compliant. PCE carries a complete line of CARB and EPA compliant pressure washers ready to go right out of the box and stay on the road. To learn all about California compliance, check your equipment, learn more about CARB and what they require, shop all compliant models, and even learn about financing options available to you, head to our California-Compliant Pressure Washers page.

Veloci Replacement Pump Kit for GP Kit 4 – Made in Italy Fit for General Pumps (49.6004)

Restore the power with this easy-to-install, quick, and long-lasting Veloci Replacement Pump Kit for GP Kit 4 made in Italy. Engineered for a perfect fit, this repair kit is designed to consistently provide professional quality in the harshest conditions.

Veloci has included every OEM part number along with well-known product names to ensure your ordering process is easier and quicker. There’s no need to decipher or match descriptions, saving you valuable time and eliminating confusion when it comes time to place your order. Plus, every part included in this kit is shown in the picture for easy reference and verification.

All Veloci components are made from high-strength, chemical-resistant materials built to withstand heavy pressure, heat, and extended use. Parts are precision-made for a snug fit to minimize leaks and wear while maximizing the long-term durability of your equipment. Craftsmanship is also a top priority, so you can be sure your tools will operate at their best performance after every repair.

Of course, it’s a good idea to inspect the rest of the pump and engine components for damage before installation. Often times, broken seals or valves are just the first sign of bigger problems, and it’s always recommended to fix those first. This way you can prevent further failures and breakdowns.

About brand

Veloci Performance Products – The Performance Technology Specialist

Driven by Innovation. Rooted in Quality. Focused on You.

Veloci Performance Products is more than a supplier—we’re your performance partner. As the exclusive U.S. provider of MTM Hydro products, we lead the industry in delivering high-quality pressure washing components and accessories trusted by professionals and DIY users alike.

Our journey began in 1977 when MTM Hydro, SRL was founded by the Costamagna family in Cherasco, Italy. In 2005, Scott Lindholm and Pierluigi Gallo partnered to bring MTM Hydro to Eden Prairie, Minnesota. With a focus on manufacturing for OEMs and distributors, the U.S. team quickly became a trusted name in pressure washing.

Following the unexpected passing of Scott Lindholm in 2011, his son Aaron Lindholm stepped in as President of the U.S. division. Over the next several years, Aaron listened to the market, rebranded the business, and launched Veloci Performance Products, Inc. By 2017, he officially became President and CEO after acquiring the U.S. operation from MTM Hydro SRL.

Today, Veloci continues to build on its legacy. Our mission is clear: to provide premium products backed by strategic support, exceptional service, and a commitment to raising industry standards. From the warehouse floor to global distribution, everything we do is grounded in one word—quality.
