Snyder Industries 70 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

A day tank that arrives in a box

Seventy gallons is a drum and a little more, and a day tank holds a measured charge where the pump can see it, with a lid that opens for a wand and a wall that will outlast the drum. The wall is sized for a liquid nearly twice as dense as water and certified against ASTM D1998, the standard rotationally molded polyethylene tanks are specified to, so the day tank carries the same listing as the bulk tank it draws from; the HDPE tank wall thickness guide explains the D1998 sizing logic. Full, it puts 1,109 pounds on a 23 inch circle at the rating, which any slab carries, per the concrete pad sizing guide; on a skid, the frame under it is flat and full-width. The tank sizing calculator sizes a day tank to feed rate and shift length, and the tank sizing guide covers the reserve.

Grades on the 23 x 42 inch tank, and the sizes beside it

The N42 is cross-linked polyethylene for hypochlorite and the other oxidizers, and the C34 and C26 are the general grades, all in the same shell at this weight. The 1009000N45 is the other certified 70, an inch shorter on the same base; the 1550000C26 holds 65 gallons taller and heavier, and the 5690100N42 lays 90 gallons of cross-linked resin down on a 34 inch base.

Outlet and manway

• Access: 8 inch threaded lid; filled by hand, wand or transfer pump, and vented outside on anything that fumes.
• Outlet: order the bulkhead fitting in the material the chemical calls for; a flexible transition to the pump suction and a small valve.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

The white wall shows the level through it, which is the point of a day tank: the operator sees the charge go down over the shift. A float switch for low level protects the dosing pump, and a calibration column on the suction lets the feed rate be checked by eye. Keep the lid closed against vapor loss, and set the tank in a spill tray; a 23 inch tank fits any of them. Label it so the fire inspector and the workplace inspector read the same thing.

Who buys this tank

A day tank for hypochlorite, acid, caustic or inhibitor at a dosing skid where the certification has to be on file, polymer make-down, a pilot vessel in a lab, and a small buffer for a well pump. One chemical per tank, labeled.

Delivery day

The 1007200N45 ships by UPS (NMFC 156600) in a carton, so the freight cost estimator shows a parcel rate for your ZIP rather than a truck, and the listed price is before freight. One person carries 30 pounds through any door. Fill it to the lid once, check the outlet fitting, drain and dry before the chemical goes in, and keep the certification paperwork with the project file. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
