Laguna is dedicated to beautifully simple water gardening. These high quality, high efficiency pumps are designed for easy installation and long lasting, worry-free performance. Laguna Max-Flo pumps are designed to provide continuous and reliable water circulation. They are ideally suited for a variety of pond applications, such as providing water flow to filtration systems and creating spectacular waterfalls. The pumps are powered by a magnetic-driven motor that"s unrivaled in the market for generating large amounts of water flow at extremely low energy costs. This is great news for people who are wary of costly electricity bills. In fact, switching to a Laguna pump will often pay for itself in as little as one season. Max-Flo pumps are suitable for multiple pond applications, such as providing water flow to filtration systems (pressurized filters, surface skimmers) and creating spectacular waterfalls. Specifically designed to provide continuous and reliable water circulation, Max-Flo pumps process water loaded with moderate amounts of suspended solids and transport them to suitable external filter systems which then trap any debris that could potentially pollute pond water, effectively filtering the pond. They are completely submersible and designed to run continuously in fresh water, for years of trouble-free operation. Laguna Max-Flo 600/900/1500/ Waterfall & Filter Pump Laguna Max-Flo 600/900/1500 Waterfall & Filter Pumps are designed to process water loaded with moderate amounts of solid particles and transport these suspended solids to suitable external filter systems (including pressurized filters) which then trap any debris that could potentially pollute pond water, effectively filtering the pond. The uniquely-shaped pump cage allows the passage of solids sized up to 1/4 inch. As always, the pump motor is unequalled in the pond industry for its ability to generate an astounding amount of water flow reliably and continuously at low energy-efficient costs. The pumps are ideal for use with filtration systems and for creating waterfalls and streams. Laguna Max-Flo 2000/2400/2900/4200 Waterfall & Filter Pump The Laguna Max-Flo 2000/2400/2900/4200 Waterfall & Filter Pumps are designed to process water loaded with moderate amounts of solid particles (or solids) and transport these suspended solids to suitable external filter systems (including pressurized filters) which then trap any debris that could potentially pollute pond water, effectively filtering the pond. The uniquely-shaped pump cage allows the passage of solids sized up to 5/16 inch. As always, the pump motor is unequalled in the pond industry for its ability to generate an astounding amount of water flow reliably and continuously at low energy-efficient costs. The pumps are ideal for use with filtration systems and for creating waterfalls and streams. Max Flo Features 1. Easy to carry handle 2. Delivers solid particles up to 3/8-inch directly to the filter 3. Universal Fast Coupling for 3/4-inch, 1-inch & 1-1/4-inch diameter hosing. 4. Fast Coupling for 1-1/2-inch diameter hosing Pump Installation General Information Since the MaxFlo Pump has ability to process water that is moderately loaded with suspended solid particles, the MaxFlo pump is ideal for use with most all filtration systems. The pumps are ideal to transport suspended solids to a Laguna PressureFlo filters which then traps any debris that could potentially pollute pond water, effectively filtering the pond. The pumps are not suitable for supplying water to fountainheads, because the fountainhead jets could easily become clogged by solids processed by the pumps. The pump motor sits inside a uniquely-shaped cage that is designed to allow the passage of solids up to a determined size only (from 6 mm to 8 mm depending on the model), as bigger solids may clog and damage the pump. The pump must never be used without its cage. For improved operation, place the pump in the deepest part of the pond. At minimum, it must be placed at a depth of 8 inches. If necessary, you can secure the pump to a fixed base by using the keyhole-shaped slots, located at the bottom of the cage, which are shaped to allow the fast engaging/disengaging of the pump from the base. The electrical cord must be protected against any objects that may potentially damage it. The electrical receptacle/socket must be located in a dry, protected and easily accessible place.

Non-Kink Hosing Pump Care Maintenance is essential and simple to carry out Once a week, verify that the pump performance is satisfactory. If you detect a drop in pump performance (such as a decrease in water flow from the pump or to the waterfall) first clean the Pump Cage and the hosing. If the water flow is still not fully restored to its original performance, clean the Impeller, Impeller Well and Impeller Cover. The Pump Cage must be cleaned at least once a month. When necessary, or at least once a year, clean the pump motor completely (Impeller, Impeller Well, and Impeller Cover) and check that no limestone deposits, which could jeopardize pump operation, are present. To keep the pump in good working order, always replace any worn parts. The pump motor has no user serviceable parts. If the motor or the electrical cord is damaged, discard the pump. TroubleshootingLow flow from the pump Check that the pump cage is clean. Check the hose for blockages. Check that the pump is free of dirt and debris. No flow from pump Check that the power supply is on. Check the fuse and wiring. Check that the plug is correctly connected to the electrical receptacle/socket. Check that the pump cage is clean. Check the hose for blockages. Check that the pump is free of dirt and debris. Check that the pump is completely immersed in water.. **Made in Italy Warranty The Pumps are guaranteed against defects in material or workmanship for a period of 3 years from date of purchase, under normal usage.
