Why The Pump, A Pressure Washer’s Workhorse, is Superior in the Landa MHC

One of the most critical components to look for when you’re selecting a piece of cleaning equipment is the actual pump. That’s the workhorse of a pressure washer. The pump is what produces the pressure so that you can actually increase the pressure of that water at the nozzle to provide the cleaning. Landa has a proprietary pump called the L-Series pump. It has three pistons and they all use U-seals which increase the longevity of the pump and provides for long-term durability. When you’re looking for a pressure washer that’s going to be used by facilities managers for a variety of applications by a variety of level of users, a durable pump is what’s going to make your pressure washer last a long time and provide reliable service year after year.

Why Landa’s Cool Bypass System With Provide a Longer Life for the Landa’s MHC Pressure Washer…

Landa’s MHC pressure washer has the flexibility of being modified with a float tank. This float tank allows you to use inlet chemical, either at high or low pressure, and it provides the ability to add a patented feature by Landa called Cool Bypass. This unique feature allows the unit to stay cool under long periods of rest. While an operator is cleaning, they might set the wand and gun down. Most pressure washers go into a bypass mode which means water is just circulating over and over again in the pump, but continues to increase stay at or increase in temperature. With Landa’s patented Cool Bypass, a little bit of water is bled off and cooler water is introduced into the pump. As a result, the pump stays cooler and helps to increase the life of the pump.

The next post in this series will explain why the variable pressure wand and flow switches are important parts of your pressure washer buying decision.
