Since our debut in 2005, we have exposed our company to the public. After around 10 years’ operation, our products have been accepted home and abroad. Our products include gear oil pump, screw oil pump, centrifugal oil pump, rotor pump, stainless pump and so on.

Combined our technology and experience, we never stop our persistence in developing new products. Not long ago, we successfully reform our stainless steel pump, which is greatly received by our clients. Our stainless steel pump can be customized according to your special requirements so that it can be applied in more and more fields. One of our customers from Yunnan ordered a batch of stainless steel pumps with special requirements, with our technicians’ careful study, we have successfully sent those pumps in ten days, which really encourages our technical team.

Just recently, Honghai release a new product, soya bean milk pump. As modern people pay more attention to nutrition, there is huge requirements for this pump. About one month time, Honghai successfully produced it, which completely solve the problem to transport hot soya bean milk, tofu and rice milk. It’s told by Honghai technical person, the inner side of this pump is silica rubber, which is a perfect heat-resistant material for the angle of health.   

Welcome to visit Honghai Pump. If there is any doubt about pump, we will do our best to provide you with quality services.

 

Honghai Eccentric rotor pump

Honghai Eccentric rotor pump

 

Brief Introduction
1. Steady delivery without pulsation, little vibration and noise
2. Outstanding self-priming ability
3. The pump can deliver the varied corrosion mediums if the proper material of parts selected. In addition, the working temperature can reach 200 °C.

Honghai Lobe rotor pump Brief Introduction low rotating rate high efficiency small volume, big flow low consumed power, strong self-priming ability, easy to operate and no oil drawing. LCX type high-viscosity Lobe rotor pump is widely used in carrying the oil and oil products(when deliver the gasoline, the copper pump leaves are neede) and transport various oil and liquid in plant, such as crude oil, paint, lubricant, glass cement, oil-based acid, toothpaste and dilute alkali liquid(soap processing) etc. Application Crude industry Lubrication industry Paint industry Glass glue industry Oil acid industry Toothpaste industry Capacity:10m3/h~100 m3/h Temperature: 140 °C~200°C Honghai is also producing rotary pump, rotary Lobe pump, and gear lobe pump.

Instructions and Maintenance In Using Honghai Pumps

1. Preparation before starting the pump 

(1) Remove the useless stuffs from the pump clean up the site. 

(2) Fill adequate amount of lubricating pump oil.

(3) Before connecting coupling, check the steering direction of the motor to see if the pump is consistent with the direction of rotation, after verification, connect couplings.

(4) Before the coupling is installed, use hand to move the shaft, which should be flexible rotating. (5) Before starting the pump, it should be filled with the delivering liquid, in order to get rid of the air, then the discharge pipe valve should be closed.

(6) When transporting hot oil, before transporting, the pump should be preheating, which is carried out by use of hot oil pump continuously being transporting. Its pump casing temperature should not lower than the inlet oil temperature 40 ℃. Preheated rate of 50 ℃ / hr. Former multistage ring section pump begins to warm up, you should press the segment, pump bracket, two side nuts right amount released, preheat and then tighten it.

(7) Check foundation bolts, and the lubricating oil and cooling water supply situation.

2. On Starting the pump

(1) A thorough examination of all the preparatory work is already perfect.

(2) Open the various instruments of the switch, turn off the pressure gauge cocks.

(3) Turn on the power supply or the starter motor when the pump reaches the normal speed, and the corresponding pressure after the meter pointed out, gradually open the discharge line valve, and adjust to the desired conditions. In the case of the discharge line closed, continuous working time of the pump can’t exceed 3 minutes.

(4) In the process, we should always pay attention to the vibration of the motor and pump power readings, the number of vibrations should not be more than 0.06 mm.

3. Maintenance

(1) Check bearing fever economic situation, bearing temperature should not exceed a temperature of standard values, and always check the oil level and oil ring, the regular replacement of oil. 

(2) Do not use the suction valve to regulate the flow, to avoid cavitation.

(3) The pump should not be less than the design flow in the case of continuous operation at 30%, if you must run continuously under these conditions, you should install a bypass pipe at the outlet, the excess traffic access to the pump inlet tubing.

(4) The constant attention to seal leakage and heat conditions.

(5) Always check for loose bolt, rotor pump inlet temperature and the temperature is consistent, vibration export gauge fluctuations and pumps.

(6) Note that the pump is running without noise, such as found in the abnormal state, promptly notify the person concerned staff.

4. Stop The Pump

(1) Gradually close the discharge line valve.

(2) Power off (or stop the turbine)

(3) After the pump to cool, and then turn off the cooling system and seal each pipeline oil. 

(4) The liquid and the cooling water pump should be empty and cleaning in case of cracking and bonding.
