Introduction:

Corrosion resistant stainless steel self-priming pump application: SFB and SFBX series pump can transport the temperature less than 90 degrees Celsius (direct coupling type) or less than 105 degrees Celsius (with bearing brackets), with (or without) have small soft particles or fiber, corrosive or health requirements of liquid, and SFB SFBX series pump has self-priming performance of two series pumps are widely used in food, beverage, medicine, wastewater treatment, chemical, electroplating, dyeing, fine chemical industry etc.

Small stainless steel self-priming pump installation instructions:

1. The connecting place of the conveying pipe of the pump device, especially the connecting place of the input pipe, must be connected reliably and well sealed.

2, SFB type pump such as the installation of the suction surface is higher than that when the inlet suction pipe should install the valve, SFBX self suction pump in suction within the suction pipe without bottom valve.

3, when transporting liquid such as bamboo, wood, stone or metal, too large or too long hard objects, suction screen must be equipped with filter screen at the inlet of the suction pipe, so as to avoid the above objects being sucked into the pump and cause the impeller to be damaged, and the motor or pump parts are damaged.

4, water pump devices usually have overload and short circuit protection devices, such as fuses and overcurrent relays, and the location of protection devices should be adjusted according to the current of motor signs.

Note: 1. The installation height of the SFB pump is 10.09- (NPSH) r-0.5-hw, and HW is the water resistance of the suction pipe.

Two, the installation height of the SFBX pump is ≈ it is allowed to absorb the vacuum height of -hw

Note two: 25SFBX-8 type, 25SFBX-8D type pump, self suction height is 3 meters, self-priming time less than 3 minutes.

The rest of the model in the pump self-priming height is 4 meters, self-priming time less than 3 minutes.

Note three and model description

50SFB-22 50---- suction inlet diameter (millimeter) SFB---- corrosion resistant centrifugal pump 22--- rated lift (meter)

25SFBX-13D 25--- suction inlet diameter (mm) SFBX--- corrosion resistant centrifugal pump 13-- rated lift (m) D--- indicates that with single-phase motor, if there is no D word, it is equipped with three-phase motor.

Materials: 1, over current parts and connecting frame: 1Cr18Ni9TI stainless steel.

2, mechanical seal: static ring: ceramic (SiC). Moving ring: graphite impregnated furan resin.

3, rubber structural parts: fluoro rubber. 1Cr18Ni9Ti stainless steel.

4, such as conveying medium or the conditions of use and the pump configuration does not match, you can configure other materials. If the overflow component is made of 316 stainless steel, the shaft seal can be equipped with polytetrafluoroethylene or other kinds of static and static rings.
