With high quality cast iron housing for the long term using.
To achieve the excellent performance, we use great VCT cable with Epoxy resin base, dry motor and dura-mechanical seals.
This series also with heavy-duty ball bearing and protector and insulation level is IP 68.
The design of centrifugal semi-open impeller which can avoid any long fiber items or other objects to block the inlet.
Both radial cutter and ring are made from SUS-440C material in which the hardness is reached HRc 55-60 . Any high tenacity objects such as leather, textile, plastic bags, and rope are easily to be grinded.
HBI and HBN series are light-duty stainless steel horizontal multistage centrifugal pumps for use with base mounted electric motors. The mechanical seal is designed for simplified replacement.
These pumps are suitable for pumping slightly corrosive liquids because product contact parts are 304 or 316 stainless steel.
STAIRS HH series is a home mini booster pump designed for water pressure boosting of potable water and residential hot water. The pump provides extra water pressure to showers, taps, and similar water fixtures, and to activate water heaters. The pump is equipped with a flow switch which starts or stops the pump when a water fixture is turned on or off. To avoid cavitation noise and risk of damage to the pump bearings, a minimum inlet pressure of 1.5 meter head is required during operation. The Comfort Home MB series pump is mainly for use in open systems, but can also be installed directly on the incoming water mains supply to feed a combination boiler, or a water heater.
STAIRS HW series residential and light commercial hot water circulator pumps constitute a complete range of 3-speed circulator pumps. The pumps can be used in both open and closed systems. HW pumps are of the canned-rotor type, i.e. pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. This pump has 130mm or 180mm port to port dimensions to be chosen.
The INVECO line of variable frequency drives is designed to control and protect pumping systems including water supply for domestic, irrigation, commercial and industrial applications; for heating and air conditioning applications; for filtering to pressure washing applications; etc.
Aquafos water tanks are suited for all water systems: industrial, domestic and agricultural. The tanks are constructed of a polypropylene liner combined with high grade butyl diaphragm to isolate water and air. This provides a closed system for drinking water preventing the growth of bacteria and vermin intrusion. The cast stainless steel water connection is used for corrosion resistance. All Stairs tanks are quality tested to insure the structural integrity of every tank.
SB, SBI and SBN vertical multistage centrifugal pumps are powered by standard electric motor.
The motor output shaft directly connects with the pump shaft through a coupling. The pump unit consists of optimized hydraulics, various types of connections, an outer sleeve, a pump head, pump base, four stay-bolts and various other parts. The pump base has suction and discharge ports on the same level (in-line). This in-line design provides a more compact design and easier installation. All pumps are equipped with a mechanical shaft seal of the detachable cartridge type. SB, SBI and SBN pumps are available with various stages and capacities to provide customers a choice of models for many applications.
SBK pumps are vertical multistage centrifugal pumps especially designed for pumping of cooling lubricants for machine tools , and to be mounted on top of tanks with the pump stack immerged in the pumped liquid. STAIRS SBK pumps are available with various pump sizes and various numbers of stages to provide the flow, the pressure and the length required.
STAIRS SD series high head submersible sump pumps are designed for commercial and industrial dewatering, groundwater transferring, effluent transferring, and car washing applications. These pumps include a stainless motor housing, and they are designed to provide great heat dissipation from the motor, ensuring a long service life. All pumps are 100% pressure-tested, submerged and run to ensure quality and reliability for years of trouble-free performance. This attention to detail is an inherent feature of every pump in this series, making it one of the most reliable in the industry.
