On the long-term idle gear pump problems arising from a few comments

Long-term idle gear pump, gear pump, arc gear pump idle does not work, when the restart will result in gear pump stuck or gear pump seal leaks, gear pump noise and other large phenomenon, there are several main reasons. Gear pump, arc gear pump idle for a long time does not work, when running again when the gear pump seal will produce leakage. The main reason is divided into two points: (1). Mechanical seal gear pump due to long-term backlog of the transmission medium in the mechanical seal end face will produce carbon deposits, especially mechanical seal pump in the delivery of high-viscosity materials, gear pump long-term Will not run the material and the mechanical seal together, when you start the gear pump again when the gear pump from the light side of the mechanical end wear and tear caused by pump leakage, then it will then twist off the mechanical seal spring gear pump, gear pump mechanical seal caused direct damage . (2) For example, ordinary cast iron gear pump in place for a long time, because the gear pump manufacturers are generally used in the gear pump experiments are repeated use of test machine pool waste oil, oil will inevitably have some, when this part contains moisture Long-term retention of waste oil in the gear pump cavity and gear and pump long-term contact due to full exposure to air oxidation and other reasons, the gear pump cavity will rust in a short period of time, resulting in gear pump installation is complete, the use of basic does not move . This situation is more common in newly installed customers, the average customer to buy gear pumps are purchased at the local shops, but often they buy these gear pumps are the owner of the inventory or backlog of products (because as a gear pump, gear Pump middlemen are required to stock, but inventory of different length) So remind our customers to buy gear pump or other local gear pump must first go gear pump spindle rotation is flexible, whether the uniform rotation, so as not to buy Going back will produce unnecessary trouble.

Transfer Pipet

Practical disposable transfer pipettes, made from natural low density polyethylene (LDPE). The transfer pipet is simple and safe to use with a long shelf life; no issues with broken glass, cracked or loose bulbs. Additional advantage is that with the single piece design lager amount can be transferred by allowing fluids in the bulb. These plastic transfer pipettes are ideal for transferring small amounts of fluids for microscopy sample preparations or to prepare mixtures or staining solutions. The extra fine tip enables transferring minute amount of fluids. These cost-efficient plastic transfer pipettes are disposable and intended for one-time use. Ideal for educational and research environments. Can be used for fluids up to 70°C, please take care to protect the fingers squeezing the bulb. Available in six sizes/styles: 0.5ml, 1ml, 2ml, 3ml, 5ml, 10ml.
