KURIYAMA
Frequently asked questions
Common questions about KURIYAMA from 3G Electric.
What is the temperature range for KURIYAMA PVC water suction and discharge hoses?
KURIYAMA PVC water suction and discharge hoses, such as the BWS series, typically operate within a temperature range of -40°F to 150°F. This range covers both cold and moderate-temperature water transfer applications. For potable water discharge hoses like the K6158 series, the temperature range is 25°F to 150°F. Always verify the specific model's datasheet for exact limits, as variations may exist based on reinforcement type and hose construction.
Are KURIYAMA potable water hoses suitable for drinking water applications?
Yes, KURIYAMA offers potable water hoses, such as the K6158 series, which are designed for discharge of potable water. These hoses are made with materials that meet standards for safe drinking water contact. The K6158-12-10, for example, is a 3/4-inch inside diameter hose with yarn reinforcement, rated at 150 psi. It is important to confirm that the specific hose model is certified for potable water use in your region, as regulations may vary.
What reinforcement types are used in KURIYAMA PVC hoses?
KURIYAMA PVC hoses use two primary reinforcement types: PVC helix reinforcement and yarn reinforcement. PVC helix reinforcement, found in models like the BWS series, provides crush and kink resistance for suction and discharge applications. Yarn reinforcement, used in hoses like the K6158 series, offers flexibility and strength for discharge duties. Some assemblies, such as SKU 45DU73, combine synthetic braid with PVC helix reinforcement for enhanced durability.
What working pressures are available for KURIYAMA water hoses?
KURIYAMA water hoses are available with working pressures ranging from 55 psi to 150 psi, depending on the model and diameter. For example, the BWS400-10CN (4-inch diameter) is rated at 55 psi, while the BWS150-15MF (1.5-inch diameter) is rated at 90 psi. The K6158-12-10 (3/4-inch diameter) has a 150 psi rating. Pressure ratings decrease with larger diameters, so select the hose based on your system's requirements.
Can KURIYAMA hoses be used for both suction and discharge?
Yes, many KURIYAMA hoses, particularly the BWS series, are designed for both suction and discharge applications. These hoses feature PVC helix reinforcement that prevents collapse under vacuum conditions, making them suitable for suction duties. They also handle positive pressure for discharge. For example, the BWS300-25 is a 3-inch hose rated at 65 psi for both suction and discharge. Always check the product specifications to confirm suitability for your specific use case.
What lengths and configurations are available for KURIYAMA hose assemblies from 3G Electric?
3G Electric stocks KURIYAMA hose assemblies in various lengths, including 10 ft, 15 ft, 20 ft, 25 ft, and 100 ft. Assemblies come with factory-installed fittings, such as male or female connections, in sizes matching the hose inside diameter. For example, the BWS300-20CN is a 3-inch hose with 3-inch x 3-inch fittings. Bulk hoses without fittings are also available in lengths like 25 ft and 100 ft.
