Drain pump or they can apply under the pretext of watering apparatus, because it is easy to pump water from wells, barrels and more buckets! Very popular sump pump "miniGnom" developed in Russia and produced by many plants. However, its main drawback is weight. Pump quite heavy – one person did not carry. For drainage of cellars or wells experts advise use of drainage and sewage pumps the cd different in terms of pressure and the cubic capacity. Kevin ulrich anchorage gathered all the information. When you select a sewage pump it is best to pay attention to the material from which made the blades of the impeller. Naturally, the best are pumps with stainless steel blades.
For example, the model series Grundof kp made of highly durable corrosion resistant chrome-nickel steel. Submersible pumps if the water table at depths greater than 8 m, without a submersible pump is necessary. He together with the pressure pipe is lowered into the borehole. And under the pressure created by the pump, the water is pipe enters the house. Among the cottagers popular submersible pump "Kid" made in Russia (the maximum immersion – up to 40 m, capacity – up to 430 liters / hr). Its advantage – unpretentious work and low price ($ 20). Among German is the most common pumps are grundfos Series sq – not very expensive domestic pumps available to the mass consumer. There is this producer and industrial pumps sp.
But they are quite expensive and require additional units of protection and management, which is also adversely affecting their popularity. Submersible pump designed to operate at different depths, it solves the problem of water supply in case deep wells, creating pressure on the water surface in the hole from 30 to 300 m. These pumps are made from expensive high-quality materials: stainless steel and metal, without affecting the quality of drinking water. Respectively, and are they are not cheap, about $ 300. There is more than 30 models of mark grundfos, which are chosen depending on the depth of wells and water needs. They are protected against dry running, power surges, equipped with soft start; check valve. The devices themselves react to overheat, disabling, if necessary, to cool the engine. These pumps are less sensitive to sand than many other submersible pumps. All parts and pump housing made of stainless steel impellers – from tehpolimera. For more popular in the Ukrainian market of Spanish pumps include four-inch pumps company espa (series Neptun fl and Saturn 4fl). This is a cheap submersible multistage pumps with built-in check valve. Units up to 1,1 kW themselves react to the overheating of the engine off in case of need for cooling. Through the application of technology floating wheels insensitive to the sand in comparison with most other submersible pumps and allow pump water containing sand and 100 gr./m3. All parts and pump casing made of stainless steel, impeller made of plastic Noryl. Such pumps are used to domestic agricultural use, irrigation and the establishment of hydro-pneumatic water supply stations. To provide the necessary pressure to operate household appliances like washing machine and dishwasher, water heater and bath tub, take setting, ie finished pumping station. It consists of a pump relay and the tank. Pump draws water into the tank, and when the pressure reaches the norm, it will automatically switch off. Without any electronic additions station wilo (Germany) will cost you U.S. $ 200-250.
