FAQs

Frequently Asked Questions

MD1 Specifications

  • Is MD1 rated NSF 61?

    Yes. The MD1 pump is NSF 61 listed.

  • How many strokes per minute?

    The CD1 and MD1 pumps have a maximum strokes per minute of 200 strokes per minute (SPM).

  • What operating voltage is my pump? how do I change the operating voltage?

    The CD1 and MD1 pumps can be operated with a wide range of incoming voltages, from 96 to 264 VAC at 50 or 60 Hz. This is because the pumps are equipped with a self-adjusting voltage feature that automatically adjusts the pump’s output voltage to match the incoming voltage. This means that there is no need to manually change the operating voltage of the pump, regardless of where it is being used.

  • The maximum suction lift is stated as 20 ft at 0 psi. what does it mean “0 psi”?

    0 psi means at 0 psig. PSIG stands for pounds per square inch gauge. It is a unit of pressure that is used to measure the pressure of a fluid above atmospheric pressure. Atmospheric pressure is the pressure exerted by the weight of the air at sea level. At sea level, atmospheric pressure is approximately 14.7 psi.

  • Enclosure specs are “NEMA 4X, Valox, PA12” what do these mean?

    Valox:VALOX are a semi-crystalline family of PBT, PET and blends with Polycarbonate (PC), offering an outstanding mix of value added properties for a variety of applications. Blue-White uses VALOX 420SE0. VALOX 420SE0 Polybutylene Terephthalate (PBT) resin is a 30% glass fiber reinforced, injection mold grade material. This brominated flame retardant PBT has a UL V0 and 5VA rating.

    PA12 is Polyamide 12 or also known as Nylon 12. PA12 is a general use plastic with broad applications and is known for its toughness, tensile strength, impact strength, and ability to flex without fracture. 

  • What is Flex-A-Prene material?

    Flex-A-Prene® Diaphragm

    Blue-White’s® Flex-A-Prene® diaphragm is manufactured from a type of Thermoplastic Elastomer (TPE) or Thermoplastic Rubber specifically designed to offer long life in chemical metering pump applications and to provide superior chemical resistance against most water treatment chemicals. The material exhibits remarkable memory properties resulting in excellent flow repeatability in diaphragm pumping applications.

    • Flex-A-Prene® diaphragm is capable of operating against system pressures as high as 150 PSI (10.3 bar) and continuous operating temperatures as high as 185F (85C). 
    • Flex-A-Prene® material fully complies with FDA 21 CFR, 177.2600 criteria for food contact. 
    • Flex-A-Prene® is a registered trademark of Blue-White Industries. 
  • What is DiaFlex material?

    DiaFlex® Diaphragms

    Blue-White’s® PVDF diaphragms, used in our CHEM-FEED® Diaphragm type Chemical Metering Pumps, are manufactured in our factory to ensure a quality product. DiaFlex® features an innovative single-layer design that exhibits zero breakdowns or delamination. DiaFlex® is designed to last the life of the pump which greatly reduces downtime and maintenance. The PVDF composition of both the pump head itself and the diaphragm ensures excellent chemical compatibility. DiaFlex® is available in three sizes to accommodate varying flow rates. 

    • The first single-layer injection molded PVDF diaphragm 
    • Zero breakdown 
    • Zero delamination 
    • 100% in-house manufacturing 
    • Longer lasting diaphragm 
    • Single wetted pump head material 
    • Patented design  
  • What is TFE/P?

    TFE/P is a copolymer of tetrafluoroethylene and propylene with a fluorine content of app. 54%. This material is unique due to its resistance to petroleum products, steam, and phosphate-esters. In some respects it exhibits media compatibility properties similar to ethylene propylene and fluorocarbon. The compression set resistance at high temperatures is inferior to standard fluorocarbons. Service temperatures are -5°C (25°F) to +204°C (+400°F).

    TFE/P provides improved chemical resistance to a wide spectrum of automotive fluids and additives. It is resistant to motor oils of all types, engine coolants with high level of rust inhibitors, extreme pressure (EP) gear lubricants, transmission and power steering fluids, and all types of brake fluids including DOT 3, mineral oil, and silicone oil. TFE/P is ideal for heat transfer media, amines, acids and bases, as well as hot water and steam up to +170°C (+340°F).

  • What is PA12?

    PA 12 (also known as Nylon 12 or polyamide 12) is a good general-use plastic with broad additive applications and is known for its toughness, tensile strength, impact strength and ability to flex without fracture. PA 12 has long been used by injection molders due to these mechanical properties. And more recently, PA 12 has been adopted as a common 3D printing material for creating functional parts and prototypes.

  • What does Hz mean? “pulses per second,” “frequency,” or “Inside Diameter”.

    Hertz (Hz) is unit a measure representing cycles per second (1/sec). For flowmeters, this correlates to pulses/second. The flowmeter will produce a frequency of pulses per second, where each pulse is equal to a certain volume of solution. 

  • What is standard pumphead connection type? Are other options available?

    Std connection type is 3/8″ od tube compression. Optional Kit-C5M = 1/2 mnpt, Kit-C5B = 1/2″ hose barb. 

  • Max Feed Rate listed is 8.50 GPH. My output is a lot less. Why?

    The maximum feed rate of the pump is determined by pumping water at a temperature of 72°F into the atmosphere, with a 5-foot suction at sea level. However, factors such as viscosity, elevation of operation, suction lift, fluid temperature, and injection pressure can affect the actual feed rates. To accurately calibrate the pump to the specific installation conditions, it is recommended to conduct a volumetric test.
