Reciprocating Pump

A: If you need to revise the product design or specification of cryogenic equipment, please let us know as soon as possible. We will work with you to understand the changes you require and provide a new design or specification that meets the need. Please keep in mind that depending on the extent of the revisions may impact the delivery timeline or pricing of the product.

A: "At Zoiun, we offer highly competitive pricing on a wide variety of solutions for cryogenic applications. We also provide further discounts for large quantity orders. In the event that you cannot find the cryogenic equipment you need on our website, we are more than happy to source promotional pricing through our sister companies to ensure that your needs are met."

A: If you need to cancel an order, please inform us as soon as possible. It's important to note that our production process begins immediately after we receive the deposit in our bank account. We have a buffer period of 1 or 2 days for returning the payment, which normally takes 1 or 2 days to get into our bank account. However, once the production has started, cancellation may not be possible and may result in cancellation fees or forfeiture of the deposit.
We understand that unexpected circumstances may arise, and we will work with you to find the best solution. If you need to cancel your order, please contact us as soon as possible and provide the reason for cancellation. We will do our best to accommodate your needs while minimizing any impact on production timelines or costs.

A: A reciprocating pump is a type of positive displacement pump that moves fluid through a system using a piston, plunger, or diaphragm. These industrial pumps can handle flow rates from 0.024 to 12,681 gallons per hour and discharge pressures up to 15,000 psi, offering precision for applications like chemical dosing pumps in metal finishing. Their ability to maintain steady flow under high pressure makes them essential for processes requiring accuracy and reliability.

A: Pump selection involves:
Flow Rate and Pressure: Match your process requirements.
Fluid Characteristics: Ensure compatibility with viscosity and corrosiveness.
Pump Type: Select piston, plunger, or diaphragm based on application.

A: They offer precision and pressure that centrifugal pumps can’t match for dosing or high-viscosity tasks.

A: A piston, plunger, or diaphragm is a primary component of a reciprocating pump. This works inside a chamber which defines the ultimate pump volume. A connecting rod is attached to a motor crank on one end and the piston, plunger, or diaphragm on the other. A suction pipe allows fluid to be drawn into the chamber, while a delivery pipe allows fluid to be discharged. Inlet and outlet valves check the flow of fluid into and out of the chamber.

A: Check for Leakage: Inspect the pump and its connections for any signs of leakage. Leaks can occur at pump seals, valves, fittings, or piping connections. 2. Inspect Valves: Check the suction and discharge valves for proper operation.

A: There are two types of manually operated reciprocating pumps—the single-action and the double-action. The single-action pump provides flow during every other stroke, while the double-action provides flow during each stroke. Single-action pumps are frequently used in hydraulic jacks.

A: Reciprocating machines are generally applied on low-flow/high-head service. Centrifugal pumps can have efficiencies as low as 40 percent on low-flow/high-head service. A reciprocating machine can have efficiencies greater than 90 percent on the same service.

A: For this reason, reciprocating pumps are typically started with an open bypass line from the discharge to the suction. To accomplish this, the operator manually opens a bypass valve, or a power-actuated dump valve is programmed to open automatically, which bypasses the liquid during the start and stop functions.
