Snyder Industries 90 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

The wide day tank

Ninety gallons is a drum and a half, and a 34 inch base under 41 inches holds it beside a dosing pump without a strap or a step, which is the shape a skid builder wants when the frame is wide and the ceiling is a bench top. 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 1,426 pounds on a 34 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 34 x 41 inch tank, and the sizes beside it

The N42 is cross-linked polyethylene for hypochlorite and the other oxidizers, and the N48 and N51 are other linear grades, all in the same shell at 43 pounds; this tank carries 7 pounds more resin for the certified wall. The 1007200 tanks hold 70 gallons on a 23 inch base an inch taller, the N45 certified like this one, and the 1012700N48 holds 100 gallons on a 30 inch base at this same height.

Outlet and manway

• Access: 14 inch lid at waist height; 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 34 inch tank fits a standard one. 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, brine for a small softener, and, with water in it, a buffer for a well pump; a fire reserve is a different tank, and the fire-water reservoir design guide sizes that one. One chemical per tank, labeled.

Delivery day

The 5690100N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. One person carries 50 pounds, and at 34 inches across it goes through a standard 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.
