LQF LQFZ Stainless steel corrosion-resistant centrifugal pump

1.Product Pverview

The company's main products are stainless steel centrifugal pumps, stainless steel centrifugal pumps with self-priming and do not take two series of self-priming.The company products are mainly applicable to transport corrosive, hygiene, are widely used in food, beverage, pharmaceutical, cosmetics, waste water treatment, chemical (or chemical) and electroplating industry.

Centrifugal pump

LQF, LQFZ series pumps are designed for corrosion-resistant centrifugal pump of stainless steel, two series of pump impeller semi-open structure, others with closed structures. Pump and motor of connection way and has straight joint type and with bearing Bay type two species, all pump of axis seal are with currently West Germany more advanced of hanging arm type technology a mechanical sealed, due to I company products set excellent structure, and performance, and made shaped Yu a, and had flow parts and the connection frame used quality stainless steel material manufacturing, so, two products has resistance corrosion performance reliable, applies, and maintenance convenient, and structure compact, and energy low, and sealed performance good, series advantages.

2. The main purpose

LQF and LQFZ series pump can conveying temperature not above 90C ° (straight joint type) or not above 105C ° (with bearing Bay type), containing (or not shouted) has small soft particles or fiber quality, with corrosion sex or has health requirements of liquid, LQFZ series pump also has carefully performance, two series pump widely applies Yu food, and beverage, and medicine, and sewage processing, and chemical, and plating, and dyeing, and fine chemical, industry using.

3. LQF model and main technical parameters

LQFZ ≈ allows vacuum suction on the pump installed height height-HW.

Note: 25LQFZ-8 type, 25LQFZ-8D type pump, self-priming height of 3 meters,  self-study time 3 minutes.

Rest each pump model carefully with a height of 4 meters,  self-study time 3 minutes.

Note III: model description

4.Material

  1. flow and connections: 1Cr18Ni9Ti stainless steel

  2. mechanical seal: static rings, ceramic (SiC) rings, graphite impregnated furan resins.

  3. rubber structure: fluorine rubber, 1Cr18Ni9Ti stainless steel

  4. such as the transport medium or use the condition and configuration of the pump when the material does not match, you can separately configure other materials. Such as flowing parts with 316, shaft seals can be fitted with Teflon or other types of rings.

5. Conditions of use

1, direct-coupled pump liquid temperature is not more than 90C °, bearing bracket type pump liquid temperature must not exceed 105C °

2, because so far is not an adaptation of any media, concentration, temperature, use of materials, corrosion medium by the user, and conditions of use should not exceed the scope of application of the pump material.

 3, the product's technical data are based on room temperature water as the medium for the determination, such as the transmission medium is not room temperature water when the pump performance will vary, please make appropriate adjustments.

6. Installation instructions

1, pump delivery pipe joints, especially pipeline connections must join a reliable installation and sealing.

2,-LQF installed above the suction fluid surface, suction tube intake foot valve should be installed, LQFZ self-priming pump self-priming suction pipe not install foot valve.

3, the transmisson fluid mixed with bamboo, wood, stone, metal, too large or too long when hard objects, filters on the suction pipe inlet must be installed to avoid jammed the above-mentioned object being sucked into the pump impeller damaged motor or pump parts. 

4, pump overload and short circuit protection device, such as fuses and overcurrent relay and should be adjusted according to the motor nameplate current protection device setting.

7. Use of pumps

1, before the start, should first pump cavity filled with fluid, starts for lack of liquid in the pump Chamber is strictly prohibited.

2, before using, you should confirm that the motor turn to use, semi-open impeller pumps right turn: click on the tail-oriented view, Ye Yingshun motor wind clockwise, right turn of the closed type impeller pump: for motor rear view, motor fan counter-clockwise, trial starts to move.

3, before use, with bearing bracket type pump should give bearing bracket cavity into the 30th lubricants, especially should be kept in the middle line of the oil immersion lens, only visible over oil, no oil shortage, resulting in damage to the bearing.

4, should pay attention to check the shaft seal, if a leak is found in serious condition, should be shut down to repair and avoid liquids into the motor cavity damage motor.

8. Service

1, this product such as failure, identified is indeed caused by, our company made from the date of purchase, one year repair, replacement, wearing parts (except mechanical seal);

2,Our tenet: credit first, customer first.
