Using a circulator pump for a domestic water recirculation system may not be enough sometimes, and this is when the wise thing to do is to research some more and find a solution to the problem. The right attitude should be to purchase a booster pump such as the Grundfos mq3-45 model.

In contrast with a normal water pump, Grundfos mq3-45 has a powerful pump that is equipped with a boosting option. The advantage of this system is that it can safely be used in domestic plumbing applications because it not only circulates the water, but also boosts its speed if necessary. This way, the potable water of some systems will have no risks of becoming contaminated because of a slow flow.

It is natural that because of this complex and useful option that the motor of Grundfos mq3-45 has, it needs to be protected somehow. This is the main reason why its manufacturers have installed a protective function and an automatic reset option. They both guard over the well-being of the unit, keeping its performance at its best and ensuring its long life.

Similar to many other water pumps, the Grundfos mq3-45 has a temperature range at which the liquid should flow in order for the device to be secure and to work properly. For this model, the range is between 0 and 35 degrees Celsius. Additionally, the maximum pressure at which it can operate is of 109psi, because of the glass fiber that forms part of the impeller and pump housing.

To conclude, this model of water pump is best for those houses with a plumbing system that will not work properly because of the slow flow of water. Due to its boosting system, this pump will not only purify the water, but it will also keep it clean and safe to drink.

History of the pumps

History pump has several millennium. Mention of the first pump is in the works of Aristotle (IV century. BC). Surmise that the Hanging Gardens of Babylon (V-VI centuries BC) were supplied with water by using a simple pump, powered by physical strength of humans and animals. Since then, the pump design has undergone many improvements, and the pump was constant companion of human life, so familiar and even mundane …

But no man is the first inventor of the pump, long before mankind on our planet already existed a “live” pumps – trees. These amazing creations of nature the main task – to pump water from the ground, performs a kind of powerful natural pump barrel. The trunk of the tree consists of a system of vertical tubes in which water is transferred from roots to leaves. Tiny pores on the leaves under the influence of solar energy evaporates some of the water accumulated in the leaf and the remaining water molecules attract moisture from the bottom. This creates a pull, forcing the roots pull water from the ground. The cumulative force generated in this way, all the pores of the leaves of the tree, is so powerful that it can move up the trunk of the hundreds of gallons of water.

Compact step-Grundfos Pumps

Compact step-up pumps Grundfos UPS15-42 is designed for a small increase in pressure in the existing water supply network (eg, in front of the instantaneous water heaters, washing machine or dishwasher). Thanks to the built-in sensor flow pump is turned on and off automatically. Seal-less pump is equipped with an electric motor with wet rotor, which is separated from the stator protective sleeve made of stainless steel. Small size and weight, the design concept “in-line pump can be mounted directly on the pipelines. When installing the pump shaft should occupy a horizontal position, junction box should stationed at the top. Low noise (less than 35dB) allows the pump directly in the home or apartment.

Grundfos Pump Stations

Grundfos Pumping station  made on the basis of Grundfos 15-58 pump, complete with pressure and diaphragm pressure tank capacity of 20 or 50 liters. With the JP pump can pump water from the well or reservoir at a depth of up to 8 m. With the built-in ejector pump is a self-priming. Housing and pump impeller are made of stainless steel, which ensures a long service life. The pump is equipped with a built-in overload protection and requires no maintenance during its life. The pump is automatically activated when the pressure decreases in the pressure tank and turns off when the desired pressure value.

Circulating Pumps Grundfos

Circulating pump – an essential element of the heating or hot water. He makes the liquid circulate in closed circuit, which increases the heat transfer in the heating system. The circulating pump can also maintain a constant temperature of water in the hot water system. The circulating pump runs continuously, so it very high requirements – simplicity and reliability, low power consumption and quiet.

Grundfos circulator pumps are designed to provide forced circulation of coolant (water) the heating, cooling, hot water and air-conditioning

To reduce noise circulators are manufactured with wet rotor.
Depending on the level of automation, pumps may provide either a permanent job, or work on a timer, or adapt to the current needs of the system.

The pressure created by the pump, serves to compensate for friction loss in pipelines and is not more than 18 meters of water (in most cases – from 4 to 8). The pressure indicated on the marking pump.
Main applications of circulating pumps

* Heating system
* Hot Water Systems
* Warm floors
* Cooling System
* Air Conditioning Systems

The working Little Giant utility pumps

* Hot water;
* Pure, liquid, not aggressive, and explosion-proof environments without mineral oils, solid or long fiber.
* Fluid with kinematic viscosity of 10 mm2 / s
* Ethylene glycol with a concentration of up to 40%.

Grundfos Circulator Pumps

Grundfos pumps circulate water for heating and hot water systems, underfloor heating. This way, the effective heat dissipation. Grundfos circulator pumps, have small dimensions and weight, operate almost silently and consume very little electricity. In order to ensure a comfortable temperature in the house, as well as to save power and heat heating system should be regulated depending on outside air temperature. To this end, UPS circulators have three speeds, and pumps UPE-electronic stepless speed. In individual homes used UPS 15-58 series pumps and UP Series 15-42  with threaded flanges R1 or R1 / 4.

Little Giant Sump pumps

To supply water from a depth of more than 8 m from the ground using Little Giant sump pumps. Three-inch pump 6-CIA is used for wells with a diameter of 76 mm. The pump is made of stainless steel and other corrosion-resistant materials. Significant advantage is the presence of Little Giant pumps built-in soft start and that is very important, built-in protection against fluctuations of voltage, overload, overheat and dry running. Small size of the pump, use a minimum of additional components and automation – all to save considerably on the drilling of wells and installation of the pump. To ensure a constant pressure in the system, regardless of the number of points, water pumping, can be used 6-cia pump with electronic speed.

Little Giant Drainage pumps

Small size and easy to maintain submersible pumps KP will help you Drainosaur pump out the clean and polluted water from drainage pits, ditches, pools and ponds. These pumps can be installed for permanent work or move from place to place. Made of stainless steel and equipped with built-in protection against running dry, the pumps have a long shelf life and require no maintenance. If necessary, the pump is equipped with a float switch, which provides automatic switching on and off the pump, depending on water levels. To clean the pump from its base mud can be easily dismantled. More
