  • Pulse Hose Benefits

    Pulse HosesPulse is an integral part of Pumptec pump systems and provides very specific benefits.

    Pulse hose is a specially manufactured hose that, unlike typical hose, will expand slightly to dissipate energy. The energy dissipation quality decreases momentary pressure spikes and smooths flow and performance.

    Each compression cycle of the pump creates a pressure spike and then no pressure. If the pressure spikes are not dissipated, system components receive the spikes and can cause premature wear, noise, lower performance and higher energy needs.

    Some of the components affected are:

    • Gauges can fatigue from the pulsations and fail prematurely.
    • In-line heaters can have coils that stress and crack.
    • Regulators can have premature seal failure from the frequent bouncing of the regulator piston with each pulsation.

    Noise will come from the hydraulic pulsations vibrating in the pump and motor, and other system components vibrating in equipment case.

    Lower performance results from the regulator piston bouncing and allowing fluid to bypass out and not go through the nozzle to create pressure.

    To compensate for the lower performance, the pressure is often adjusted higher resulting in higher energy requirements during spray and then during bypass.

    The proper length of hose is critical for optimal system performance. Pumptec-designed systems have the proper length of pulse hose to provide optimal performance. If you are in need of a reference for your system design, please use the ratio of 6 ft of total pulse hose for every 1 gpm of flow as a guide.

  • Proper Care and Maintenance of Pumptec Pumps

    ‘With proper care and maintenance, your pump should provide years of service....’ is a common statement in Owner’s Manuals, but the specific practices are seldom described.

    For Pumptec pumps, there are a few simple practices to follow to keep the pumps in proper working order.

    1) Pumptec pumps are intended to pump ambient temperature clear water and water-based solutions in the 7 pH range (Standard chemicals).  Solutions that do not fit this description may be able to be pumped, with additional care and consideration (Non-standard chemicals). Under no circumstances is it recommended to pump volatile chemicals like gasoline, acetone, etc... These high VOC chemicals are prohibited.

    2) After use with a non-standard chemical, the pump should be flushed with clear water and left with only clear water inside until the next use. Chemicals left inside the pump can corrode and damage internal parts and surfaces resulting in rapid wear.

    3) Hot liquids, greater than 120 F, can cause damage in the pump and erosion failure. Hot water is unstable and can flash to gas during the pumping process causing cavitation which will erode and pit the pump body parts. If hot water must be used, it needs to be pressurized either by placing the tank above the pump (up to 130F) or by the use of a booster pump (beyond 130F).

  • Plunger Pump vs Diaphragm Pump

    Pumptec’s 12V-powered plunger pump technology provides many advantages over gas engine-powered diaphragm pumps.

    12V powered equipment offers the benefits of quiet operation, extended operation and ‘green’ technology.

    12V motors are much quieter than gas engines and draw less attention to work being done. For example, if you are in the pest control business, but your client does not want to call attention to the services you are providing to their residence, a 12V pump system will quietly do the job. Quiet operation also benefits lawn care professionals by increasing the hours of service available to them. In many areas, there are noise restrictions that limit the hours a gas engine can be operated. A 12V system would not be controlled by this rule.

    12V systems use batteries with extended run times beyond the gas tank capacity of some engines. The operator does not have to stop during a job to fill the gas tank or adjust the throttle. With a 12V system, operators can ‘refill’ their batteries driving between jobs if their system is wired that way.

    There is more negative attention than ever towards gas engine-powered equipment. Gas prices, oil dependency and pollution are issues that will continue and may get worse. There exists a positive image of 12V technology as a future, environmentally-responsible power source. Users of 12V equipment may receive more business as a result of these trends in the market.

  • Application spotlight: Portable bathroom cleaners

    Pumptec has played a key role in the decrease of biological dangers in institutional restrooms and similar facilities.

    In cooperation with the creative people at Kaivac Inc, Pumptec developed a compact pumping system used as the heart of their unique line of cleaning equipment specifically purposed for cleaning large restrooms and other similar hard surface environments. Pumptec’s powerful pump and integrated chemical injection system made possible Kaivac’s vision of a portable machine that would allow the operator to successfully perform ‘no touch’ toilet and bathroom fixture cleaning.

    Imagine bringing dignity back to cleaning a toilet and at the same time providing a method to clean an area and leave it significantly more germ-free than other methods that simply apply more chemical and then smear it all around.

    The Kaivac system uses a chemical solution applied at low pressure and then uses high pressure water spray to clean it away. The result is a surface with little to no biological leftovers to transmit disease. www.kaivac.com

    Pumptec supplies the pump system for a similar type of equipment manufactured by Karcher North America. Although the system is different, the result of a clean area is the same.

    Both companies, along with Pumptec, are creating better environments with lower disease hazards. and that benefits everyone.
