VIEW DETAILSRockySea Petro Mechanical Diaphragm Metering PumpDescriptionDiaphragm metering pumps use flexible diaphragms to replace pistons. Driven by the drive mechanism, the diaphragms move back and forth, changing the pump chamber volume, and absorbing and discharging liquids under the action of the pump inlet and outlet valves.Diaphragm metering pump can be used to transport corrosive and non-corrosive liquids without solid particles in a quantitative manner according to the needs of various process fl
VIEW DETAILSRockySea Petro Mud PumpDescriptionIn the operation of using rotary drilling method to drill oil and natural gas wells, the drilling reciprocating pump is used to pump drilling fluid, i.e. mud, to circulate and flush the well. During drilling, the mud pump injects mud into the wellbore along with the drill bit, playing a role in cooling the drill bit, cleaning drilling tools, fixing the wellbore wall, driving drilling, and bringing rock cuttings back to the surface.So drilling pumps are usually

VIEW DETAILSRockySea Petro Plunger Metering Pump
Application Data
1. Hot residue in vacuum distillation (200 ℃, solid)
2. Mix four items (resin, pigment and accelerator) in the production of plastic film
3. Measurement of viscous bromine based catalyst in margarine production
4. Adding glucose syrup in the candy industry
Feature
RockySea Petro plunger metering pump has the following advantages.
1. The diameter of the plunger can be very small, generally D6-200mm.
2. The flow is within the range of 10% - 100%, the metering accuracy can reach ± 1%, and the maximum pressure can reach 50MPa.
3. The discharge pressure range of the plunger pump is wide, and it should be made into a high-pressure pump.
4. It can be made into various types of heat preservation pump heads (steam, hot water, electricity and other heating pump heads), and can be made into multiple sets in parallel for adding different liquids, different flows and pressures.
5. The shaft seal is a packing seal with leakage. The preload of the packing shall be adjusted periodically. The packing and plunger are a pair of wearing parts.
6. Simple structure, convenient maintenance, good cost performance.It can transport high viscosity medium, not suitable for transporting corrosive slurry and dangerous chemicals.
Operation principle
The hydraulic end of the metering pump forms a working chamber with the help of a plunger, which makes the volume of the working chamber change periodically in the reciprocating linear motion. Working principle: the motor drives the worm through the coupling and decelerates through the worm gear to make the spindle and eccentric wheel rotate, and the eccentric wheel drives the sliding adjusting seat of the bow link for reciprocating motion. When the plunger moves backward to the dead point, the pump chamber gradually travels to vacuum, and the suction valve opens to suck in liquid. When the plunger moves forward to the dead point, the suction valve is closed, the discharge valve is opened, and the liquid is discharged when the plunger moves further. In the reciprocating operation of the pump, continuous pressurized and quantitative discharge liquid is formed.
RockySea Petro Petro: A Pioneer in Plunger Metering Pump Manufacturing in China
The plunger metering pump directly sucks and discharges the working medium through the reciprocating motion of the plunger. RockySea Petro both the plunger and the seal are in contact with the medium, selecting the appropriate plunger material and seal form can ensure that the pump has ideal performance during operation. RockySea Plunger metering pump includes valved pump and valveless pump. Plunger metering pump is widely used in petrochemical industry because of its simple structure and high temperature and pressure resistance.
