Summary of pumps

SRP Series swing rotary pump is a sort of new positive-displacement pump invented by Hichine Industrial (Beijing) Co., Ltd.

This pump has peculiar advantages on its structure and performance, such as strong self-priming capacity, gas-liquid mixing

transfer property, which can ensure a normal function of Model SRP under different working conditions. SRP Series swing

rotary pump suits to transfer media the temperature of which rangesfrom -40℃ to 80℃ like gasoline, kerosene, diesel oil,

aviation fuel, lubricating oil etc.

Oil products, chemical liquids or any other possible gas pumping applications, like materials delivery of oil depot, condensate

pump, liquefied gas pump, train chute, fueling of automobiles, cargo stripping on oil ships. The applicable flow rate ranges from

0 to 200m3/h, outlet pressure from 0 to 3.0MPa, and viscosity from 0 to 1520cst. Small dimensions, large flow rate, high lift,

strong suction capacity of piston, high efficiency, gas-liquid mixing transfer are outstanding characteristics for this model of

pump.

Main features:

1. With only a length of around 0.01～0.03mm for the seal line locating between rotor and cylinder wall, it thus has strong

self-priming capacity, its limiting vacuum can reach 99%, and so can replace vacuum pump for siphoning and stripping. The

suction if up to 6m can be completed in 7--8s.

2. Excellent gas-liquid mixing property, can transfer the mixtures with a ratio from 0 to 100％.

3. Wide range of application, suitable to transfer media from high to low viscosity, media with different viscosity can be mixed

together in transferring.

4. No vulnerable parts except sealer; the only friction is generated by core and cylinder body, but ultra-low linear speed and

wearing cannot affect pump performance, and thus no need to replace it.

5.Little variation for its suction performance either at low or high speed, little variation for the limit vacuum, can produce pumps

with must NPSH of 0.5～1.5m.

6.High efficiency of over 72％.

SRP-Z pump

Overview Model SRP-Z pump consists of one high-duty centrifugal pump and one swing rotary pump. Suitable for loading of clean cargo

or chemical liquid on rail cars, ships. The max.outlet lift can reach 60m, and the max. flow rate600m3/h; strong self-priming &

cavitation performance, suitable for siphoning, stripping, tank cleaning, transferring in replace of vacuum system. This model of

pump can eliminate the problem of the air lock arising from gasification of clean cargo

Features

1. Safe to use,

no release of flammable gas for this model, the removal of water ring vacuum pump eliminates the risk if careless to let in oil,

gas or other chemicals or out of vacuum pump water tank;

2. energy-saving, cost-effective

In summer, to use vacuum pump for loading gasoline would not only bear loss of more than 150l arising from volatilization, but

also require extra electricity consumption, while the use of SRP-Z has a normal electricity consumption and little volatilization, in

addition the removal of vacuum system and pump house can save a lot of money.

3. Easily handling

The removal of vacuum pump leaves oil unloading operation to model SRP-Z pumps; 2 valves are needed in the pump house,

pumps working in parallel can directly complete unloading, stripping, transferring etc, thus greatly reduces the workload of

workers.

4. Greatly upgrading of anti air lock performance

To make rotary pump and centrifugal pump work in parallel can eliminate the air suction arising from gasification of media so as

to turn centrifugal pump into a normal and smooth function. It still can work even if the temperature rise to 40℃.

5. Two pumps can be separated; highboy mounted, suitable for motorized unloading.

Typical application

1. Unloading of train tanker in oil depot or chemical plants.

2. Loading, stripping on ships.

3. Tank cleaning

4. Movable unloading system
